A stand-off jammer broadcasting wideband nose causes many problems for a tracking algorithm and is one of the Electronic Counter Measure (ECM) techniques employed in the benchmark problem, Benchmark problems for tracking maneuvering targets have been very helpful in the comparison of proposed algorithms because the problems address some 'real world' tracking issues such ECM, false alarms, and target maneuvers. An accurate estimate of the jammer position and power can be accomplished with passive tracking or through the use of the non-target detections during main- lobe jamming. Recent work in the area of monopulse processing provides a method for debiasing the target measurements in the presence of a jammer and employs dwell averaging through the use of multiple frequencies. Proper beam-pointing is also required to maintain an accurate target track. This paper presents a method for tracking maneuvering targets in the presence of jamming as defined by the benchmark problem. Simulation results that illustrate the performance of the measurement debiasing technique and beam-pointing control are also presented.
