Abstract

The invention provides an operating distance analysis method on the basis of a space-based infrared detection system. A movement track of an infrared moving object is modeled, and thermodynamic analysis and temperature distribution simulation are carried out on the modeled infrared moving object; the infrared radiation amount of the infrared moving object is calculated and obtained according to a result of temperature distribution simulation of the infrared moving object; the infrared radiation amount in the atmosphere transmission process is calculated and obtained; and the radiation energy, of the infrared object, received by an area-array staring detection system, reaching an expected using effect is calculated and obtained, namely, the maximal operating distance that can be detected by infrared detection system for the infrared moving object is obtained. The detection accuracy and instantaneity of the infrared moving object are improved, and searching, detecting and tracking for the infrared moving object can meet requirements.

Description

Technical field [0001] The invention belongs to the technical field of detection and search of infrared moving targets, in particular to the research field of infrared radiation characteristics of infrared moving targets and atmospheric background, and specifically relates to a method for analyzing the range of action based on a space-based infrared detection system. Background technique [0002] The detection and tracking of infrared moving targets of typical aircraft is the core issue in combat defense systems. Research on the detection range of infrared moving targets is the premise and foundation of infrared moving target detection and tracking. In modern warfare, radio radar detection is still in a dominant position. However, radio radars often work with larger transmission power. Today, with the highly developed electronic warfare technology, they are often easy to become targets of anti-radiation attacks, and their battlefield survivability is seriously challenged. In this...
