Research on low-altitude penetration tactics simulation of anti-stealth aircraft

In order to study the effectiveness of low-altitude and ultra-low-altitude penetration of stealth aircraft under the condition of electronic jamming, the influence of low altitude penetration tactics on radar detection performance is studied based on the dynamic radar cross section (RCS) of a typical stealth aircraft and the reflection effect of the ground on electromagnetic waves. Firstly, the RCS of the aircraft is calculated by using the coordinate transformation matrix and the high frequency approximation algorithm. Secondly, the radar and jammer antenna pattern propagation factors F and F_j are introduced to characterize the reflection effect of the ground to the electromagnetic wave, and the radar equation is derived to obtain the radar detection range and detection probability. Finally, the stealth aircraft penetration scene is simulated, and the influence of parameters such as flight altitude and ground undulation on radar detection performance is analyzed. The simulation results show that the low-altitude and ultra-low-altitude penetration tactics can significantly reduce the detection performance of radar to stealth aircraft, and the ground reflection effect has an obvious impact. The research results can provide a theoretical reference for the flexible application of the tactics in combat training.
