Abstract
Method of slowly moving target detection with application for coastal surveillance radars. This method improves the well know other methods and efficiently detects targets with a high accuracy. The proposed method consists of three steps that are: step of generation and processing of signals with complex modulation; step of target clustering and step of detection of slowly moving targets in clutter environments.
Claims6
A method of detecting a slowly moving radar target in clutter environments comprising the steps of:
- Step 1:
- generate and process signal with complex modulation, in this step, a signal with complex modulation, high range resolution and high compression ratio is generated;
- Step 2:
- target clustering, in this step, all targets are clustered by their radial velocities to 2 groups (slowly moving targets and fast moving targets);
- and
- Step 3:
- slowly moving target detection by using together three detectors that are 3D OS-CFAR detector, detector based on statistical analysis and detector based on a clutter map.
