单脉冲精密测量雷达速度消模糊算法仿真及性能分析

在测量雷达中,由于采用了低重频,当fr〈2×Fd时,就产生了Fd的测量模糊。文章对不变量嵌入法和线性估计法两种速度消模糊方法进行了介绍。并通过仿真,对比两种方法在非滑窗方式和滑窗方式下消速度模糊的效果,得出线性估计法是一种能够快速准确解速度模糊的方法的结论。

Emulation and Performance Analysis of Elimination of Velocity Ambiguity in Monopulse Accurate Instrumentation Radar

In instrumentation radar,it will produce instrumentation ambiguity of doppler frequency when the repetitive frequency is less than double doppler frequency because it uses low repetitive frequency.The paper describes two eliminating velocity ambiguity methods of invariant embedding method and linear estimation method.It contrasts the eliminating velocity ambiguity effect of two methods under the non-sliding window way and the sliding window way through simulation and it also draws the conclusion that linear estimation method can eliminate velocity ambiguity quickly and accurately.
