| 摘 要： | 连续波体制雷达由于是全占空比工作,发射功率很低,使其具有一定的低截获概率性能;连续波雷达扩谱容易,易于实现高距离分辨;同时该体制雷达具有无距离盲区、时宽带宽积大等特点,正是由于这些不同于普通脉冲体制雷达的特点,近年来,随着理论和器件水平的提升,连续波体制雷达越来越受到大家的重视。着重讨论了某线性调频连续波雷达试验系统中频率合成信号源的设计与实现,并给出了试验结果。

| Abstract: | LFMCW radar operates with full duty cycle and very low transmitting power,so it is provided with Low Probability of Interception(LPI) characteristic.In addition to easy to spread frequency spectrum and achieve high resolution,LFMCW radar is provided with no distance blind area and large time-bandwidth product.Because of these characteristics,LFMCW radar attracts more and more attention along with development of theory and device.This paper deals with the design and realization of frequency synthesizer on LFMCW radar experimental system,supplies test result. |
