Active cancellation stealth analysis based on interrupted-sampling and convolution modulation

In this paper, a radar cancelling stealth system for linear frequency modulated signal is proposed. This system is based on interrupted-sampling and convolution modulation. The basic theory of active cancellation stealth is introduced. Based on three conditions that should be met for radar echo cancellation, the restrictions for three key parameters are deduced in theory. The influence of amplitude, phase and frequency error have been discussed. And the cancelling scheme and working principle are also introduced in detail. Finally, numerical simulation results show that the active cancelling approach is feasible and effective.
