Inter-channel CFAR detector

In multichannel pulse Doppler surveillance radars, parallel signal processing is used in several time - spatial channels, i.e. range-azimuth-elevation. Time-spatially differenced data give radar output picture about targets existence, position and moving parameters. A data fusion center synthesizes differenced channels data to provide continuous reliable tracking and displaying. Targets move over flying area across time-spatially channels, including “null“ space occurring between antenna beams. The concept of non-coherent inter-channel statistical CFAR detection based on antenna beam forming is introduced in this paper to obtain continuous inter-channel even-detection output.
