基于综合测频法的脉内特征分析

综合测频法通常由搜索测频法和非搜索测频法这两种体制的测频方法结合而成。非搜索测频法瞬时测频范围大，但测频精度较低；而搜索测频法的瞬时测频范围小、测频精度较高，通常用非搜索测频法来引导搜索测频法，以近似过零检测和小波变换方法为例，对低信噪比下的典型雷达信号进行了仿真分析，结果验证了综合测频法提取信号脉内特征的有效性。

Extraction of the In-Pulse Characteristics of Signals Based on the Combined Frequency Measurement

Combined frequency measurement is customarily composed by scout frequency measurement and in-scout frequency measurement.The in-scout frequency measurement has the performances such as wide range of instantaneous frequency measurement and low precision of frequency measurement,and the scout frequency measurement has the performances such as narrow range of instantaneous frequency measurement and high precision of frequency measurement.Customarily,the in-scout measurement is used to induct the scout measurem...
