Study on the Answer Submarine Search Efficiency of Aerial Magnetic Detection

According to the characteristics of the answer submarine search of aerial magnetic detection,the paper optimizes the course angles of expanded helix search path of anti-submarine airplane.And the model of search probability of aerial magnetic detection is established to choose the optimized expanded helix search path.At the same time,the influence of the changes of submarine course and velocity on the search time and probability is experimentally simulated and analyzed.The results lay the foundation for the optimization use of aerial magnetic detection.
