Micro-Doppler shift induced by precession is crucial for ballistic target recognition. However, traditional single radar has the limitation of single viewing angle, while radar network (RNW) …
A new class of iterated linearization-based nonlinear filters, dubbed dynamically iterated filters, is presented. Contrary to regular iterated filters such as the iterated extended Kalman …
