摘要

对421 GHz相干雷达进行第一次分析，以探测距离1公里处生物粒子云的存在。在相同的战场条件下，与非相干雷达性能相比，相干系统实现了大约300倍的调后信噪比，并且远优于探测和误报警的概率。

Toward the detection of bioparticles by radar in the THz region

A first-pass analysis is carried out of a 421 GHz coherent radar to detect the presence of a bioparticle cloud at a stand-off of 1 km. Compared to the incoherent radar performance under identical field conditions, the coherent system achieves a post-demodulator signal-to-noise ratio roughly 300 times higher and far superior probabilities of detection and false alarm.
