Effects of Barometric altitude delay on the fire control system impact point accuracy and flight test method of using the GPS differential correction 气压高度滞后对火控系统靶试精度影响及采用GPS进行修正的飞行试验方法
The theory and algorithm for low altitude target localization based on time delay estimation ( TDE) is studied. 研究了基于时延估计的低空目标声测无源定位理论与算法。
It is concluded that low altitude radio fuze channel is a doubly-spread channel, through which a signal propagates will experience both time delay and frequency spreading. 指出低空无线电引信信道是双展宽的时变信道,即引信接收到的地面回波是会同时产生距离扩展和频率扩展的双扩展信号。
