Target detection and tracking are the essential functions of modern SONAR systems. Once the direction of arrival is estimated the target is tracked continuously in bearing and the target spectral information is used for classifying the target. A continuous and reliable tracking method is essential for getting the spectral information and classification of the target. Conventional tracking methods...
This paper will specifically undertake the task of improving the passive sonar system using self-organizing map. Localizing multiple targets is a challenging problem as passive sonar sensors are only able to detect the targets' bearing angle. An effective way to find the targets location is by triangulation. However, in multi-sensor multi-target environment, ghost targets are introduced during the...
This work is concerned with the tracking of passive sonar targets (bearing and Doppler measurements), by maximizing the probability density in the presence of noise. We exhibit a deterministic particle filtering technique that allows high performance with a reduced number of particles. Simulation results are given, including the case of unknown manoeuvres from the target, represented by a priori Poisson...
