考虑了相干跳频雷达在脉冲压缩和频域干涉测量中的应用。建立了考虑有限波束宽度影响的匹配滤波器接收机输出端双频相关分析模型。分析仅限于垂直雷达波束的情况。利用这一结果推导出有效的高度加权函数，该函数可以通过对多个频率的接收机输出进行适当的叠加得到。该结果还用于研究频域干涉技术中的归一化相关或相干性。说明了有限波束宽度对高度分辨率和相干函数的影响，并讨论了该技术的实际应用和局限性。
The use of a coherent frequency-hopped radar for pulse compression and frequency domain interferometry is considered. An analytical model for the two-frequency correlation at the output from a matched filter receiver is developed that includes the effects of finite beam width. The analysis is restricted to the case of vertically directed radar beam. This result is used to derive the effective height weighting function that can be obtained by appropriate superposition of the receiver output from multiple frequencies. The result is also used to study the normalized correlation, or coherence, which is used in the frequency domain interferometry technique. The influence of finite beam width on the altitude resolution and coherence function is illustrated, and practical applications and limitations of the technique are discussed.
