Modeling Target Detection and Performance Analysis of Electronic Countermeasures for Phased Radar

Interference is a key factor in radar return misdetection. Strong interference might make it difficult to detect the signal or targets. When occurs sidelobes of antenna pattern, Sidelobe Cancellation (SLC) and Blanking are two unique solutions solve this problem (SLB). Aside from approach, probability false alert likelihood detection most essential parameters radar. The chance alarm for any system should be minimal, as result, high. There several cancellation strategies literature that used sustain consistent alarms regardless clutter environment. With necessity methods constant rate (CFAR), Maisel SLC algorithm has been modified create new recognizing targets presence severe interference. received returns simulated non-stationary sidelobe cancelled using an adaptive algorithm. By comparing performance algorithms, simulation results shown. In situation, demonstrate considerable increase target recognition noise ratio when compared previous technique.
