The MiG-23M's radar is pretty special compared to them, as instead of being a proper pulse-doppler radar, it uses something called MTI with external coherence to filter out ground clutter by comparing the doppler shift of returns. Over true pulse-doppler radars in WT, the primary advantage is: contacts are displayed in azimuth vs range instead of azimuth vs closure rate, since as mentioned it isn't doppler shift that's being directly measured, instead it's essentially used to filter clutter, because the ground return is used as a reference, it only works at low altitude (which is why it automatically switches as described below), you are limited to a relatively small search pattern because of the method's limitations. The MTI mode is the one we're all here for, because you can see it as a somewhat unique early radar solution to the limitations of pulse-doppler radars of that time, and has its own advantages and disadvantages because it isn't a true pulse-doppler radar (like the RAF Phantoms and T-2/F-1 are getting in WT). See a real view of Earth from space, providing a The MiG-23M's radar is pretty special compared to them, as instead of being a proper pulse-doppler radar, it uses something called MTI with external coherence to filter Severe Weather AccuWeather Ready Winter Center. It is difficult or impossible to separate the radar image of low-flying aircraft from the surrounding ground clutter. Various weapons systems (including guns and missiles) are then employed against designated radar targets, either relying on the aircraft's radar employing the "look down" capability (as in semi-active radar homing) or the weapon's own active radar to resolve the indicated target (as in active radar homing). Active. This will explain what modes are being switched and why. This is highly desirable, as it allows an aircraft to detect and attack targets whilst maintaining the tactically advantageous position conferred by superior altitude. Airborne intercept radar relying exclusively on time domain radar techniques is effectively blind any time the radar's antenna is aimed towards the Earth's surface. Since the radar is linked to the aircraft's fire control system, it can provide targeting information to weapons once it has detected a moving object. Try searching for a city, zip code or point of interest. The technical challenge encountered by airborne radar is discerning relatively small radar returns (e.g. The radar removes all stationary objects (e.g. By accepting all cookies, you agree to our use of cookies to deliver and maintain our services and site, improve the quality of Reddit, personalize Reddit content and advertising, and measure the effectiveness of advertising. thus: in WT's "default mode", the following radar modes are used at these altitudes: you have no indication of when these modes are active beyond I think maximum range scale (30km for SMV, 30 60 90km for BSV.

Language links are at the top of the page across from the title. When will the wildfire smoke ease in the Midwest, Northeast? Look-down/shoot-down radars have been enhanced with electronic programs that process the radar image and search for moving objects, which are detected by looking for Doppler shifts in the radar return. Also a disclaimer: all this radar stuff is wayyyyy more complicated, but this is as much as I can understand with my lack of proper electrical engineering/radar knowledge. To break it down, you have 6 modes: Search Pulse Doppler Velocity (PDV) Pulse Doppler (PD) Track lower overall range, plus "blind velocities" because of wave phase wizardry (that probably isn't represented in WT) compared to normal pulse-doppler radars.

I think what you were trying to say is that British Phantoms had a better a plane flying towards you). is supposed to have additional processing over BSV to separate ground returns via how they take longer to reach the radar than the target return, but in WT there doesn't seem to be a difference from BSV aside from the elevation angle, (I'm unsure whether BSVdH is BSV-H1 or BSV-H4.

"Coherent pulse-doppler" differs from true pulse-doppler radar as instead of directly measuring a target's doppler shift, it's a pulse radar that uses a target's doppler shift as compared to the ground's doppler shift to filter out clutter.

"moving target indication with external coherence" seems to mean that unlike a true pulse-doppler radar which has precise control over the phase/frequency of emitted radar pulses (aka internal coherence), it simply does the aforementioned thing of using the (external) ground returns as a reference signal and comparing incoming returns to that (in frequency and phase), which requires less advanced circuitry. each mode has two submodes for low and high altitude, which automatically switch with radar altitude and cannot be overridden. That is because pointing the radar at the ground produces a large reflection. https://en.wikipedia.org/wiki/Look-down/shoot-down#cite_note-4, https://en.wikipedia.org/wiki/McDonnell_Douglas_Phantom_in_UK_service#cite_note-21. By using techniques to effectively remove clutter, human operators and computers can focus on targets of interest. This chart shows a view of problem reports submitted in the past 24 hours compared to the typical volume of reports Military air combat vehicles that lack this capability are blind to targets below and along the line of the horizon and therefore unable to engage or attack them.[2]. the additional clutter filtering doesn't appear to be present for its section in the file, so I assume it's slightly simplified/genericized in WT and represents both modes). Apologies for the massive wall of text but the TLDR covers basically everything you need to know unless you're intrigued about the (still overall) details.

Once the radar can "look down", it is subsequently desirable to "shoot down". also the only mode with pulse-doppler, BSVdH - high altitude pulse mode, antenna elevation centered -4 (down). This zone can be actively utilized by enemy combatants wishing to hide from radar tracking utilizing a technique known as terrain masking. Dangerous storms to slam central US to mid-Atlantic. The Discovery Channel. The Soviet Union introduced its first look-down/shoot-down radar with the Sapfir-23P on the Mikoyan MiG-23 interceptor.

TLDR: WT MiG-23 radar, two user-switchable modes, default and LD (look-down), each has low and high submode automatically switched <1500m >1800m: default low (SMV): pulse, +4 antenna elev. Adrian. A radar system has look-down/shoot-down capability if it can detect, track and guide a weapon to an air target that (as seen by the radar) is silhouetted against the ground. When speaking of coalition air operations during the 1991 Persian Gulf War, General Charles Horner described the F-15's look down/shoot down radar , "During the first three days of the war, when control of the air was greatly contested, what it basically amounted to was the Iraqi aircraft would take off, pull up their landing gear, and blow up."[6]. so simply stated, the main difference between it and a true pulse-doppler radar is that instead of measuring and displaying the exact relative velocity/closure rate/interpreted doppler shift, it instead uses the doppler shift of the ground (in the radar sidelobes) as a reference signal and the doppler shifts of any returns are compared against it. F-15. In WT, the following modes from that list are available, with these characteristics from the file: SMV - low altitude pulse mode, antenna elevation scan centered at +4 (up), BSV - high altitude pulse mode, antenna elevation centered +4 (up). From my understanding, the F-4J was the first fighter craft in the world to have Look-Down Shoot-Down capability. Currently: Hurricane - Category 2, approximately 445 mi from the southern tip of baja california. and our Also if you flew the MiG-23M on dev you may have noticed the modes switching around on their own. virtually zero clutter, but with weaknesses of this radar mode (described below).
