TBD netted radar system in presence of multi false alarms

Track before detect (TBD) in netted radar system in the presence of multi false alarms is proposed and studied. The proposed structure uses TBD algorithm based on Polar Hough Transform (PHT). This algorithm improves the detection probability of moving target along a straight line in conditions of multi false alarm. The advantage of the proposed approach is the data unification in a net of asynchronously working radars with different accuracy characteristics and each radar varied observation sampling period. The obtained simulation results illustrate the high effectiveness of this detector in the presence of false alarms. We study the detection probability of TBD multiradar system as a function of SNR and the false alarm probability for different radar number. The study is performed through Monte-Carlo simulations in MATLAB computing environment.
