With the advantage that antenna pattern and scanning features can be described conveniently in phased array radar, direction cosine coordinates (COS) is widely used. Unfortunately, measurements reported in the COS are non-linear relative to the target states described in the Cartesian coordinates. In addition, it has been proved by the theory and practice that the tracker can perform better by making...
Tracking ground moving targets with airborne radar cannot guarantee track quality and continuity due to high target density, high clutter, and low visibility. In order to solve this problem, all kinds of aided information are widely utilized in different ways. As to a kind of aided information given as geospatial map, this paper proposes a new aided knowledge fusion method. Via performing the road...
Ground moving target indication (GMTI) radar utilizes Doppler frequency shift caused by the relative radial speed of target and the radar platform to distinguish ground moving target from surface clutter. But the radial speed becomes zero when the ground target is stationary or rotates around the radar platform. Then, the target measurement will be mistaken for surface clutter and removed, leading...
Since the cognitive radar was presented, dynamic waveform selection schemes have provided the optimal transmitted or received waveforms under certain criteria, based on the prior information of the target and environment, achieving the tracking performance improvement. This adaptive waveform solution has been paid more and more attention as advances in modern information processing techniques and...
