描述了工作频率为 225 GHz 的实验性相干脉冲雷达。该系统使用脉冲锁相扩展交互振荡器发射器和由锁相耿氏振荡器泵浦的 4 分频混频器作为接收器。准光圆极化双工器将发射器和接收器信号组合到同一天线中。提供的结果包括对 3.5 公里范围内目标的检测以及对卡车和履带式车辆的多普勒频谱的观察，其中显示了车身和履带的贡献。 >
An experimental coherent pulsed radar operating at 225 GHz is described. The system uses a pulsed, phase-locked extended interaction oscillator transmitter and frequency divided by 4 subharmonic mixer pumped by a phase-locked Gunn oscillator as the receiver. A quasi-optical circular polarization duplexer combines transmitter and receiver signals into the same antenna. Results presented include the detection of targets out to ranges of 3.5 km and observations of Doppler spectra of trucks and tracked vehicles which show contributions from both body and tracks. >
