多普勒测距

A detailed analysis is made on the echo's Doppler spread and range spread caused by body target spread, and on their influence on ranging.
从理论上分析了由于体目标引起的引信回波信号的多普勒展宽和距离展宽问题，以及它们对近距离扩频测距的影响。
The vehicle also has a Doppler ranging radar to measure the distance between the vehicle and lights, so it can compute the lighting intensity and then obtain the isocandela curve.
（）λ校正的条形照度传感带在水平面内动态扫描助航灯光发光截面，利用车载多普勒测距雷达测量距离，计算相应的光强值，并进而获得等光强图。
The subject of this paper is the Doppler shift impact in pseudo-code ranging system and its capture and elimination methods.
本文研究的课题是伪码测距系统中多普勒频移的影响及其跟踪与补偿方法。
Because of the Doppler sensitivity of Pseudo-random code, the ranging ability of Pseudo_random code phase modulation fuse is significantly reduced when the speed between the bomb and the target is high.
由于伪码信号的多普勒敏感性，伪码调相连续波体制引信在弹目接近速度较大时定距性能大大降低，减少了伪码调相引信的应用范围。
