Abstract

The invention belongs to the field of research on the combat use of infrared systems in complex marine environments, and relates to a two-step calculation method for the effective range of a new shipborne infrared detection system under sea fog conditions. The two-step calculation method for the effective range of the new shipborne infrared detection system under sea fog conditions includes the following steps: the first step is to perform the first step calculation based on the sea fog concentration data to obtain the theoretical detection range; the second step is to establish an evaluation model to obtain the detection capability index; the third step is to perform the second step calculation based on the detection capability index. Based on the actual field investigation and research, the present invention proposes a two-step calculation method to obtain the effective detection distance of the infrared system in sea fog. The calculation model comprehensively considers the three-party interaction factors of people, marine environment and equipment, and effectively solves the problem. This solves the problem of "calculation failure" caused by relying solely on sea fog information.

Description

technical field [0001] The invention belongs to the research field of combat use of an infrared system in a complex ocean environment, and relates to a two-step calculation method for the effective action distance of a ship-borne infrared detection system under sea fog conditions. Background technique [0002] Among the various detection methods included in the shipboard equipment, the infrared thermal imaging detection system has attracted more and more attention from all over the world due to its outstanding advantages such as passive detection, light and flexible equipment, and low false alarm rate of targets. The shipborne infrared system can not only work day and night, but also can make up for the lack of radar detection and realize all-round and full-time detection and tracking. These advantages are very important. In times of geopolitical tension, where warships are often required to keep track of targets, and radar exposure is often considered a provocative act, pas...
