Multitarget tracking and monopulse signal processing for spawning targets

A monopulse radar is able to derive accurate angular measurements via intelligent processing of its sum and difference channel returns. Recently there have emerged techniques for angular estimation of several unresolved targets, meaning targets that are, in principle, merged within the same radar beam, can be extracted separately. The key is the joint exploitation of information in several range bins. Here we show the performance of this approach in a high-fidelity simulation: we observe considerable improvement in track RMSE, but little corresponding gain in track completeness. Coupled with a hidden Markov model on target number, however, the performance is impressive.
