According to some assumpted conditions,an air-borne radar search for diesel submarine detection rate model to evaluate searching efficiency and detection probability is developed.

Using the defections as a sample, which were found by the helicopter patrol and manual patrol, and the particular statistical analysis is based on the aspects of defection position, the discovery rate and the threat value.

Quantitative algorithm of detection probability for single shipborne radar and the functional simulation;

Detection probability evaluation model based on texture feature of thermal infrared

Based on characteristics of joint fire damage and actions of artillery,starting with the key index of survivability,an evaluation model for detection probability and damage probability is established to simulate and analyze the survivability of artillery.

Therefore,the method of circular acreage overlay can be used to establish a dynamic model of torpedo detecting probability.

The relationship between positioning precision of navigation system and detecting probability of fighter for intercepting is established.

Based on the analysis of target ship s discovering probability against anti-ship missile, the penetration problem of anti-ship missile has been researched under the condition of the target ship taking various ways against homing missile, and then ,the calculation formula of the penetration probability of anti-ship missile have been obtained.
