“…Especially in recent years, the use of infrared for target detection and identification has become increasingly common. Correspondingly, the use of water spray to control the infrared radiation from targets is becoming more common [6] . Since a flat plate structure is one of the typical shape structures of a target, it is valuable to calculate the cooling of a flat plate structure in real-scale space and analyze the change of its infrared radiance to grasp the characteristics of the target as well as to design the water spray rationally.…”

In this paper, the cooling calculation and analysis of the flat plate structure containing internal heat source is carried out, and a relatively complete calculation model consisting of continuous phase control equation, discrete phase equation and mass, momentum and energy conservation equations of liquid film is established, which realizes the calculation simulation that can be applied to the cooling heat transfer of water spray in large space. Calculations show that the trend of calculated results in this paper and the experimental data are consistent. The maximum difference between the average water film temperature and the measured temperature on the infrared imager is 1.9°C, and the maximum difference between the calculated temperature of the flat plate and the 9-point average temperature of the thermocouple is 0.9°C. The water spray cooling of the flat plate is calculated to reduce the temperature of the experiment plate by 16.5℃ in 34 seconds, and the infrared radiance of 3~5μm is reduced by 45.5%, the infrared radiance of 8~12μm is reduced by 24.2%. The water spray cooling has a significant effect on the infrared characteristics of the plate.

“…Among them, ship target identification method based on radar echo signal [11] has long operation time, wide coverage, strong detection ability [12] and high accuracy. However, when the number of radiation sources is too large, echo signals will overlap, and factors such as ultra-high speed motion and sea clutter will affect the identification results [13] [14] . The ship target recognition technology based on satellite remote sensing image can clearly reflect the color environment of multiple targets, but its acquisition cycle is long, and it cannot recognize the monitored targets in real time [15] .…”

Infrared ship target recognition technology can automatically detect, analyze and identify ship targets, which is suitable for various types of working environments. This paper takes ship target image as the research object, and measures the effect of existing infrared detection technology, traditional target detection technology and target detection technology based on depth learning through data comparison. For infrared detection and target recognition, its working principle is summarized, and its ability to quickly identify ship types in practical applications is verified. The application and development status of Sea area planning、 supervision and Military reconnaissance field are summarized, and the future development trend is prospected
