摘　　要：基于行业领先的多目标雷达测速技术,研制一种新型驼峰测速雷达,其高频部分采用微波集成电路(MMIC),取代传统的微波组件;中频部分采用专用雷达微处理器进行数字信号处理,取代传统的模拟电路;采用调频连续波(FMCW)工作制式,实现对多溜放车组的多维参数测量,具备抗邻道干扰、抗雨水干扰、低速测量稳定、高温工作稳定、单台雷达同时测量两股道等优越性能。Based on the industry-leading multi-target radar speed measurement technology, a new type of hump speed measuring radar is developed. Its high-frequency part uses microwave integrated circuit(MMIC) to replace the traditional microwave components. In the intermediate-frequency part, a special radar microprocessor is used for digital signal processing to replace the traditional analog circuits. The frequency-modulated continuous wave(FMCW) working mode is adopted to realize the multi-dimensional parameter measurement of the rolling cars set, which has excellent performances such as anti-adjacent cars interference, anti-rain interference, low-speed measurement stability, high-temperature operation stability, and simultaneous measurement of two channels by a single radar.
