| 摘 要： | 通过对单矢量传感器各通道输出不同形式的组合可以抑制干扰噪声,但高次乘方和最小均方误差准则2种方法包含非线性运算,使目标信号产生失真;常用的线性运算方法只能完全抑制与目标方位相差一固定值的干扰信号。对单矢量传感器各通道授予不同的权重系数并进行线性运算,根据最小噪声功率输出准则,在不降低目标信号信噪比的同时,通过调节权重系数,可抑制各向同性噪声场中任一方位的强干扰信号。仿真显示:本方法可在不降低目标信号信噪比和保证目标信号不失真的前提下,完全抑制与目标方位相差70°～290°范围内任一方位的强干扰噪声。

| Abstract: | Single vector sensor output of each channel with different combinations can be used to suppress interferential noise.But the method of higher order power and minimum mean-square error rule include nonlinear calculation and caused target signal distortion.The common linear calculation method can just suppress the interferential noise of fixed direction between target.Weight coefficient are set for single vector sensor output of each channel.In isotropic noise field,the interferential noise of any direction c... |
