雷达高度表回波捕获技术研究

Study on Capture Technique of the Echo in Radar Altitude Meter

为了对雷达高度表回波信号进行采集以确定回波前沿形状与地貌的关系，建立雷达高度表的测高模型，从而提高其测高精度，需要对回波信号进行准确定位．根据雷达高度表的工作原理及工作条件，特别是回波与杂波共存的条件，给出了一种回波的捕获算法及其实现电路，并进行了性能分析．

Its necessary to locate the echo in the radar altitude meter exactly in order to acquire them and find the relationship between front edge shape and landforms. The altitude measuring model is built to improve the altitude measurement precision. On the basis of the principles and operating conditions of radar altitude meter, especially the echo and interference exist concurrently, a capture algorithm and its circuit implementation are given, and its performance analyzed.
