摘要: Orthogonal netted radar systems (ONRS) can fundamentally improve performance by using a group of specially designed orthogonal polyphase code signals. However, the existing numerical solutions only address autocorrelation and cross-correlation properties with result that signals degrade severely in presence small Doppler shifts. In context these problems, new hybrid set which combines single frequency pulse signal, is presented to implement compensation keep ONRS good resilience target firstly estimated based on interpolated FFT time span compensated signal be constructed maintain tolerance. The construction illustrated. Simulation results show proposed effective for moving detection ONRS.
