多角度和偏振遥感可解决传统遥感所不能解决的大气探测和目标识别等方面的问题。为实现气溶胶偏振信息的多角度探测，提出了一种新型的多角度偏振辐射计。该辐射计可以在多个角度上测量大气的偏振光谱信息，为大气光学和微物理特性的高精度反演提供重要的实测数据源。作为航天载荷的原理样机，多角度偏振辐射计的光机系统由多路并行望远光学模块组成，可在110°视场范围内，以0.5°间隔实现偏振信息的多角度探测；采集控制与数据传输系统由双控制核心和高速接口组成，大大提高了系统的并行处理能力和数据传输速度，可在高速运动的平台上实现多路偏振光谱信息的同步采集与实时传输，避免了由平台移动和信号的异步采集引入的误差。航飞试验结果表明，多角度偏振辐射计可实现气溶胶偏振信息的高精度探测。

Multi-angle and polarized remote sensing can solve the problems such as atmospheric sounding and target recognition which cannot be solved by traditional methods. To implement the multi-angle detection of aerosol polarizing information, a new type of multi-angle polarimeter is proposed. This polarimeter can obtain polarizing spectral signals of the atmosphere on different angles, which provides a measured data source for the precise retrieval of the optical and microphysical characteristics of the atmosphere. As the principle prototype of a spaceborne instrument, the opto-mechanical system of the multi-angle polarimeter is composed of multi-channel parallel telescopic optical modules to realize the multi-angle detection of polarizing information within a view-field range of 110° and a sampling interval of 0.5°. With the design of dual controlling units and high-speed communication interfaces of the sampling control and data transporting system, the synchro-sampling and real-time transportation of the polarizing signals on multi-spectral channels has been fulfilled even on a high-speed platform, which eliminates the measurement errors brought in by platform movement and asynchronous acquisition of multi-channel signals. The on-flight experimental results show that this instrument can realize the high-precision measurement of aerosol polarizing information.
