A New Single DIFAR Sonobuoy Target Location Algorithm

摘要

In order to solve the problem of target location of single direction finding and ranging（DIFAR） sonobuoy, a new target location algorithm is proposed. Based on the new generation of high performance sonobuoy signal processing platform, the new algorithm makes full use of the Doppler information of the targets while using the target location data, and success- fully implements the target detection, location and tracking. In the calculation of target parameters, the new algorithm utili- zes the repeated measurement data to further improve the calculation accuracy of the target parameters using the principle of Least Square. The simulation results indicate the correctness of the new algorithm. The algorithm is simple, stable and easily implemented in engineering. And besides, it overcomes the weakness of the traditional algorithm which requires at least two DIFAR buoys to locate the targets.
