Time Modulation in Phase Switching Screen for Target Stealth

Phase-switched screens (PSS) has the characteristics of dynamic regulatory radar scattering direction, and traditional PSS can only analyze the reflection state under infinite large size without considering the angle scattering. Here we introduce the time modulation theory to PSS for corner scattering analysis, which can realize the frequency spectrum movement of the target stealth in radar-tar get-receiver chanel transmission. The simulation analysis can be realized without signal reflection at the center frequency by switching different array elements. When the opposite phase array reaches the opposite, the sidelobes of the diagonal diagram can be effectively suppressed.
