Abstract

Abstract:

To precisely analyze the output signal of tracking circuit in a four-element infrared detection system and provide an accurate computational basis for the guidance and anti-jamming algorithms, this paper delves into its operational principle. Considering the missile spinning, the target image trajectory generated by combining the four-element infrared detection system with conical scanning is simulated. The information signals and target acquisition signals of four-element infrared detection system with and without interference are analyzed by taking a man-portable air defence missile as an example. Based on these findings, the signal simulations of pulse analog tracking and digital tracking circuits are accomplished, and a simulation software for the four-element infrared detection system is developed. Through simulation experiments, it is discovered that the direct simulation of output signal from four-element detection system without taking into account the missile spinning leads to the errors in the output signal simulation results of tracking circuit. When there’s only a target spot in the detector’s field-of-view, the target can be accurately captured and and its azimuth information is calculated from the detector output. However, when the interference spots present, the target acquisition signal output becomes abnormal. Both pulse analog and digital tracking circuits can compute the azimuth information of target, but the pulse analog tracking implementation is more intricate.

Key words: man-portable air defence missile, four-element infrared detection system, conical scanning, pulse analog tracking, digital tracking
