| 摘 要： | 针对目前对Gram-Schmidt(G-S)自适应零点控制算法的研究大多只停留在理论研究阶段,还没有将其应用于低截获概率(LPI,Low Probability of Intercept)雷达设计,提出一种改进的G-S自适应零点控制算法应用于连续波(CW,Continuous Wave)体制LPI雷达。该算法可以把接收信号中的目标信息去除,只留下干扰信号,进而进行正交化处理,从而防止目标信息被当作干扰抑制掉。阵列方向图、零陷深度和误差分析等仿真结果表明:该算法在保证较快的收敛速度和较好的稳定性的基础上,相对于传统的G-S正交法有10 dB以上的零陷加深,从而验证了该算法能有效提升雷达的LPI性能。

| Abstract: | For the problem that the researches on Gram-Schmidt(G-S) adaptive null forming algorithm are still theoretical researches and there is no study on its application to LPI(Low Probability of Intercept) radar,a method of applying modified Gram-Schmidt(G-S) adaptive null forming algorithm to continuous wave(CW) radar is proposed.This algorithm can remove the target signals from the received signals and just leave the jamming signals to be orthogonalized,preventing that target signals are treated as jamming sign... |
