This can then make a small or developing Hook Echo difficult to diagnose due to the smoothed data. The radar overshoots the low-level signatureA low radar cross section antenna based on band-notched absorber is described in this paper. Firstly, the band-notched absorber is formed by introducing a notch band with full reflectance performance into a wider absorption band. For each absorbing cell unit, two independently magnetic and electric resonances with adjacent resonant frequencies are employed to develop the notch band, while a ...The Radar Cross Section (RCS) currently implemented in DCS is a single static value for each aircraft. For example, the RCS of the in-game F-16 is 4.0, Su-27 is 5.5, and an A-10 is 10.0. This current system has its drawbacks, namely that the value is completely static and doesn't change based on the aspect of the aircraft or external mounts.
