Abstract

In this paper, by using the theoretical analysis and computer simulation method, the lower boundary requirements of the infrared imaging sensor are analyzed when detecting the thermal surface features of the wake behind a moving underwater body. Firstly, the computer simulation model of the underwater body wake’s surface temperature field and the corresponding surface infrared features are established. Secondly, the measures of the sensor’s detection performance and the computation method of these measures are described. Thirdly, by using the infrared features’ simulation model and the performance measures, we have done simulation tests to analyze the given infrared imaging sensor’s detection ability for detecting underwater body wake, and the requirements of infrared sensor to detect the wake’s infrared surface feature under some given working states are also investigated. Lastly, the simulation results and the conclusions of the paper are given. The problem-solving flow chart and the simulation results on underwater object wake’s detectability given in this paper may be useful for the designment and performance evaluation of the infrared imaging sensors.
