基于多普勒信息的近程目标参数估计技术

Estimating the Short-range Target Parameters Base on the Doppler Shift Information

当鱼雷与目标之间存在相对速度时,接收到的回波信号的载频就要相对于原来的发射信号的载频产生多普勒频移,利用多次观测到的回波信号的多普勒频移信息,提出两种可用来进行近程目标参数估计的方法,仿真结果验证了方法的有效性。

Doppler Shift will be produced when the torpedo has a velocity to the target. Two methods have been present to estimate the short - target parameters base on the Doppler Shift information. Computer simulations are executed to test the performance of the two methods.
