主动雷达导引头工作波形研究

摘要

Two kinds of normal working waveforms of pulse Doppler radar are introduced and analyzed in this paper,and the quasi-continuous wave modulated signal is studied in detail,then an effective anti-eclipse method under high-PRF is proposed.Also the linear frequency modulated waveform commonly used in radar seeker is analyzed,then the signal functions and the flow charts of signal process are given,and the signal parameters are analyzed.Based on these methods and the development trend of the radar seeker,the design concept for multiple working waveforms system is presented to give the reference for the working waveform practicality design of the radar seeker.%对两种常见的脉冲多普勒雷达工作波形进行了详细的研究和介绍,重点分析了准连续波,提出了一种高重频下有效抗遮挡的方法,分析了线性调频波形,给出了其信号表达式和信号处理流程,对其设计参数进行了分析,在此基础上结合雷达导引头的发展方向提出了多工作波形体制的设计思想,为雷达导引头工作波形实用化设计提供参考。
