D-band detector for active terminal-sensitive projectile

摘要:

随着工作频率和带宽的提高，无线电近感探测器的测距精确度、目标识别能力和抗干扰能力相应提高，因此开展了D波段主动近感探测器的研究。基于120 GHz收发芯片TRA_ 120_001，对D波段近感探测器进行方案设计。为提高探测距离，设计了半球型透镜天线并制作了样品。搭建了角反射器为目标的旋转扫描下落实验场景。实验中，近感探测器在设定目标方向给出了触发信号，实现了近感探测功能，并验证了测高触发的能力。

Abstract:

With the improvement of frequency and bandwidth of fuse, the accuracy, target identification ability and anti-interference ability of detector are correspondingly improved. Therefore, the research on D-band detector for active terminal-sensitive projectile is carried out. Based on 120 GHz transceiver chip TRA_120_001, a D-band detector is designed. In order to improve the detection distance, a semi-spherical lens antenna is fabricated. The experimental scene of rotating scan falling with angular reflector as the target is built. In the experiment, the detector sets the target direction, gives the trigger signal, realizes the detection function and verifies the ability of range measurement.
