介绍了一种对野外化学云团进行实时监测的被动红外遥感技术，详细分析了红外辐射基本传输方程和各种光谱特征，并由此对干涉仪性能指标及鉴别器的鉴别能力提出了具体要求。外场试验说明，随着试验样本的不断完善，系统对信号的鉴别能力将愈来愈强。
A passive infrared remote sensing technology for real-time monitoring of field chemical clouds is introduced. The basic transmission equations of infrared radiation and various spectral characteristics are analyzed in detail. The requirements of interferometer performance index and discriminator identification are put forward . Field experiments show that as the test samples continue to improve, the system’s ability to discriminate signals will become stronger and stronger.
