| 摘 要： | 为了解决单脉冲雷达体制中距离分辨率与实际探测距离之间的矛盾，现有雷达一般采用（线性）调频中断连续波（FMICW）体制。根据模糊函数定义推导出（线性）调频中断连续波信号的模糊函数，并对重复周期FMICW信号的距离和多普勒分辨性能进行了分析与研究。分析结果表明，FMICW信号的距离分辨率仅与其发射波形带宽有关，而多普勒分辨率仅与其相干积累时间有关，这对进一步研究雷达新体制有一定的帮助。

| Abstract: | In order to solve the contradiction between range resolution and the detection distance in monopulse radar system,the existing radars often use(linear) FMICW system.According to the definition of positive-type ambiguity function,this paper deduces the ambiguity function of FMICW signal,and then analyzes the range resolution and Doppler resolution of coherent pulse train.Results show that the range resolution of FMICW signal is related to its bandwidth and the Doppler resolution is only related to its cohere... |
