Analytic comparison of four robust algorithms for post-detection integration

Four radar integration algorithms are compared with the basic moving window (video) integrator. The algorithms are robust in the sense of immunity against strong interfering spikes. Very strong spikes can appear if several radars operate in close proximity. The algorithms have been previously suggested for integration or are borrowed from CFAR thresholding methods. This paper provides an analytic performance analysis for a simple signal (Swerling II), noise and interference model. The comparison of the four algorithms, in the situation covered by this model, may be indicative of their relative performances in more realistic models, for which it is more difficult to obtain closed-form results.
