Research on Probability of Detection of Submarine Time Limit Based on Continuous Time within Finite Region

Abstract

The sonar detection of underwater submarines in a certain sea area was modeled by using the sonar in the sea area. The problem of continuous detection time of underwater large random targets was studied based on the fixed detection points. According to the characteristics of the target’s motion, this paper puts forward the research method of detecting the probability of finding the time limit of the random moving target by fixed point detection, establishes the random constant velocity target distribution model under the target initial position distribution, uses this model to carry on the duration. The effective probing time and the redundant probing time exist in the probing and continuous probing times. The probabilistic trend of the probing probability under the probing limit time decreases with the increase of the distance between the probing point and the distribution center. The effective probing time length increases with the probing point The distance from the center generally increases, but there is no linear rule.
