Do you have to keep radar lock after you have fire your radar missile? How is it possible for people to launch like 4 at different targets at the start of a match? How do you avoid them?It just reduces the sensitivity in a very narrow range (24.190-24.210 30db reduction). It does not block the signal completely in that range. I would not call it very narrow. That's a good chunk of the range. Also, when enabled, I've proven that mine blocks more than just that range, both a little higher and a little lower.Fig. 6 shows the radar system's tracking results for the small UAVs.Figs. 6 a and b are the UAV tracking results at 1000 and 2000 m, respectively.

Notching works best at longer ranges and at shorter ranges dodging the missile iis easier to pull off and avoid the deflection shots. Be below the enemy and have the ground behind you, only notch at beyond 10km and dump chaff while doing it. 4 BMO_ON • 2 yr. agoPoint the second: there's a section on the wiki about the recommended technique to counter pulse-Doppler radar, and it's not flying low, it's 'notching': turning perpendicular to the attacker so that you have the Doppler signature of a stationary object. Caution: my most advanced aircraft is a F-104A, so I've never dealt with this in practice.Different radar applications and modes will require different transmit waveforms and this is quite a large subject in itself.

If you are told to jump in his notch, turn to beam. The idea is to hide in the doppler clutter notch. Note that vertical separation is important here, this won't work well if you're at 40k and attacker is at 25k (remember the background).Notching means flying perpendicular to, and usually below, the radar source.

This almost always means the other plane, as it's their radar guiding the missile. However, in the case of active radar homing missiles, you will need to notch their radar instead, at least once the missile goes active. These missiles usually guide using the host aircraft's radar at longer range, then switch to their own radar in the nose of ...What is radar notch? The notch is a curved line not a straight one. Fly with a bank angle into the radar you are attempting to defeat. AHR missiles: When the missile goes active apply the same concepts to the missile but not the aircraft that fired it.
