摘要
介绍了一种民用船用导航雷达射频子系统架构。采用X波段线性调频连续波体制,结构上采用当前流行的两单元设计。收发天线分离,使用微带阵列双天线,和射频前端集成安装在一个基板两侧。最终装入天线罩后,整体尺寸为φ60*25 cm,包括天线罩的总质量不超过5 kg,总功耗小于20 W。雷达的主要功能是对多批目标进行连续探测和跟踪,显示目标的点迹、航迹、速度、航向等参数。
The architecture of a RF subsystem of civil marine navigation radars is introduced. With the adoption of the X-band LFMCW system, it adopts a currently popular two-element structure. The separate T/R antenna, the microstrip array double antennas, and the RF front-end are integrated and installed on both sides of a base plate, and finally covered by the radome with overall dimension of φ60 ＊ 25 cm. The gross mass of the radome is less than 5kg, and the total power consumption is less than 20W. The main function of the radar is to continuously detect and track multiple objects, and display their plots, tracks, speeds and courses.
