Abstract

The University of Massachusetts has developed two high-power portable polarimetric radars operating at 95 and 225 GHz. The 95 GHz polarimeter employs an extended-interaction klystron amplifier capable of 1500 W peak power output. The system is configured to measure the complex scattering matrix of a target by transmitting a pair of orthogonally polarized pulses in rapid succession. A noncoherent 225 GHz polarimetric radar which directly characterizes the target Mueller matrix by transmitting a sequence of six polarization states has also been developed. The 225 GHz system utilizes an extended-interaction klystron oscillator that generates a 60 W peak power pulse. The authors review the design of the 95 and 225 GHz radars, and highlight significant measurements and applications.<>

脉冲极化毫米波雷达,利用扩展相互作用放大器和振荡器管
马萨诸塞大学开发了两种高功率便携式极化雷达,工作频率分别为95 GHz和225 GHz。95 GHz偏振计采用扩展交互速调管放大器,峰值输出功率为1500 W。该系统通过快速连续发射一对正交极化脉冲来测量目标的复杂散射矩阵。研制了一种非相干225 GHz极化雷达,该雷达通过发射6个偏振态序列来直接表征目标米勒矩阵。225 GHz系统采用扩展交互作用速调管振荡器,产生60 W峰值功率脉冲。作者回顾了95 GHz和225 GHz雷达的设计,并重点介绍了重要的测量和应用。
