Higher-dimension detection of targets from scanned radar

The detection of targets from a coherent radar scan is examined, as well as how sophisticated signal processing techniques may be incorporated into such tasks. Techniques of coherent constant-false-alarm-rate (CFAR) detection are discussed for this scanning-mode problem. In an attempt to better utilise the information present in the scan plane for detection, the use of higher-dimensional analysis techniques is discussed. The fundamental advantage is their ability to provide spatial separation (in these higher dimensions) of signal features, which it is hoped will enhance the detection performance. A method, employing such techniques, is presented, and contrasted with traditional CFAR approaches. Some examples are presented using real data, collected with McMaster University´s X-band coherent radar
