Waveform Design for Netted Colocated-MIMO Radar System
摘要
Abstract
Waveform design is one of the key technologies in radar signal processing for the netted collocated Multiple Input Multiple Output(MIMO)radar system.To improve the target detection capability of the system under clutter interference while taking into account hardware compatibility,good ambiguity and pulse compression properties of the designed waveform,the paper considers constructing a model for the radar output Signal to Clutter and Noise Ratio(SCNR)under constant modulus constraints and waveform similarity metrics;then by equivalent transformation of the original non-convex problem,a polynomial-time iterative algorithm based on successive convex approximation is proposed and analyzed for convergence.To further reduce the computational complexity,the paper also proposes an algorithm based on Gradient Projection(GP).Finally,the proposed method is simulated and verified,and the results show that the method can provide a new feasible method for the waveform design of each transmitting site under the netted radar system.关键词
