Firstly, jamming energy and radiation characteristics of the band were summarized; then, the energy and characterization were characterized with infrared radiation energy level; and then, based on the above theory, energy measurement of infrared radiation was simulated and developed, including choosing and apply design of detectors, analogue signal processing and digital signal processing, detecting and calculating energy with relative detecting methods. At last, the specific realization methods and advantages of the infrared measuring device were introduced. The experiment result shows that the response time of the infrared radiation energy measurement device is less than 2.5 ms, and detection sensitivity is better than 2.5108 cmHz1/2W-1. Energy measurement system based on infrared radiation type successfully implements the accurate measurement of long wave infrared energy to the 1-21 m with higher sensitivity and lower response time.
