An IMMPDA filtering algorithm is presented for radar management and tracking maneuvering targets in the presence of false alarms and Standoff Jammer. The performance of the designed algorithm is evaluated by Monte Carlo simulation. The results obtained over six benchmark test scenarios demonstrate that the tracking filter satisfy the performance restriction on a maximum allowed track loss of 4 %, posed by the benchmark problem. The achieved average sampling interval is approximately 2.85 sec and the average power is about 8.24 W. The paper reports preliminary results of an ongoing study and further investigation is under way
