毫米波步进频率单脉冲雷达及其信号处理

毫米波步进频率雷达通过多脉冲相参合成处理来获得距离高分辨率，而单脉冲雷达和差波束测角具有较高的测角精度和抗干扰能力，可以在很短的时间内获得目标的误差信息。文中详细分析了毫米波步进频率单脉冲雷达获取目标角度和距离信息的原理，从数学角度给出了分析的模型，并对模型的输出信号作了仿真，说明了毫米波步进频率单脉冲雷达既能获得高的目标距离分辨率，又能获得较精确的目标角度信息。该文为毫米波步进频率单脉冲雷达的工程实现提供了有力的理论依据。

MMW Stepped Frequency Monopulse Radar and Its Signal Processing

MMW stepped frequency radar obtains high range resolution by synthetic processing of phase reference of multi-pulse. While angle measurement of monopulse radar with the sum and difference beams bears out the higher accuracy of angle measurement and capability of anti-jamming, thus can extract the error information of target in a short time. In this paper the principle by which the MMW stepped frequency monopulse radar obtains the angle and range information of target is analyzed, the analytic model is built in mathematical relationship, and the model of output signal is simulated. It is explained that the MMW stepped frequency monopulse radar can obtain high range resolution and accurate angle information of target. A convicrive base is provided for engineering implementation of the radar. processing
