Analysis of Speed Measuring Precision on Airborne Doppler Navigational Radar

多卜勒导航是一种自主式的导航系统 ,但其实时测速精度较低。本文由现役多卜勒雷达的构成原理和电路结构出发 ,分析了造成多卜勒雷达实时测速精度低的原因 ,提出了提高多卜勒雷达实时测速精度的一些措施 。

Doppler navigation is a kind of independent navigational system, but its real time speed measuring precision is comparatively low. On the basis of the principle and circuit of the active Doppler radar, this article analyzes the causes of the real time low speed measuring precision and puts forward some measures of improving the real time speed measusing precision of Doppler radar.
