| 摘 要： | 在舰载、地基等高分辨率雷达的修理或研制过程中,需要对其进行测距、测速标校以检验该雷达系统性能指标。设计了一种超宽带相参雷达目标模拟器,在X波段上实现1.3GHz带宽,并以我国某海基超宽带、高分辨率雷达为适用对象,通过空馈方式接收海基雷达发射的调频步进频信号,对其进行相应的距离、速度、幅度调制后重构发射信号,再由天线辐射给海基雷达,从而模拟空中目标的各种运功状态,完成对高分辨率雷达参数校验及性能测试。

| Abstract: | It needs range calibration and velocity calibration to verify detection performance of the radar system,when some high-resolution radar such as ship borne radar or ground-based radar is repaired or processed development,a coherent ultra-wideband radar target simulator is presented,implemented 1.3 GHz bandwidth on the X-band in the paper.a ultra-wideband,high-resolution sea radar as research objects,the Stepped frequency FM signal through the air feed is received from the sea radar.And its corresponding range,speed,amplitude information are modulated and reconstructed to transmit the signal,the ethos signal is captured by the radiation antenna of sea radar,thus a variety of status of targets is simulated in the air,completion of high resolution radar parameters calibration and performance testing. |
