Interrupt CW Approach for IF Video Signal Real Time Simulating and Its Validity

To determine the feasibility and practicability of interrupt continuous wave (CW) approach proposed for real time simulating radar intermediate frequency(IF) video signal, theoretical analysis and computer simulation were used. Phases at two linked points between the end and beginning of adjoined frames are always consistent; the bias Doppler frequency for the time delay of A/D sampling start responds to that for target acceleration. No digital phase compensation is required at continuous points, and the interrupt CW approach has apparently practical values.

调频间断连续波雷达信号处理分析与仿真

调频连续波雷达具有诸如低峰值功率,低截获概率以及高距离分辨率等优势。然而,其主要缺点是对收发天线较高的隔离度要求。这通常导致采用两个独立天线用于发射和接收。一些方案采用调频间断连续波技术使得调频连续波雷达可以用一个天线工作提高收发隔离度。本文对调频间断连续波体制雷达信号进行分析,利用二次FFT处理算法解决频谱延展造成虚假目标的问题,同时给出了调频间断连续波重复频率选择的约束条件,最后在MATLAB中进行了仿真验证。
