Abstract:

In the field of hyperspectral remote sensing imaging, the demand of indicators for hyperspectral remote resolution, hyperspectral resolution and large width of imaging loads are improved. To solve the problem that the electromagnetic interference (EMI) of the high-speed electronics of spaceborne hyperspectral imaging is becoming more and more intensive, the target design method to enhance the electromagnetic compatibility (EMC) capability of the spaceborne hyperspectral imager is proposed, and the implementation of the load on a specific series of high resolution hyperspectral imager verified the effectiveness of the targeted design. In order to seek the theoretical methods and technical implementation methods of EMI design for high-speed hyperspectral imagers, the useful explorations is made to provide a useful reference for the design of other spaceborne high-speed imaging loads for remote sensing.

Key words: electromagnetic compatibility (EMC), EMC design, hyperspectral imager, high-speed imaging circuit
