“…This simulation result is also in agreement with the result of the work done by Armstrong and Griffiths [18]. In their analysis, they have also assumed a linear detector and have shown that among CA-, CAGO-and OS-CFAR processors, the OS-CFAR processor is the most susceptible of the three to the effects of spiky clutter.…”

“…In general, the probability density function (pdf) of the K-distribution is given by The 'spikiness' of the K-distributed clutter is heavily dependent on the value of the shape parameter a [15,16,17,18]. The value of a generally lies between 0.1 for very spiky clutter and cc for overall Rayleigh clutter where its probability density function becomes…”

“…were proposed to model the pdf of the amplitude of non-Gaussian sea clutter [14][15][16]. Among these distributions the compound -distribution is widely used to model the clutter and many existing contributions analyzed the radar performance considering the compound -distributed clutter [17][18][19][20]. For the sea clutter both in the sum and difference channels, the compound -distribution can not only depict the amplitude distribution accurately but also explain the scattering mechanism of sea clutter well.…”

The effects of compound K-distributed sea clutter on angle measurement of wideband monopulse radar are investigated in this paper. We apply the conditional probability density function (pdf) of monopulse ratio (MR) error to analyze these effects. Based on the angle measurement procedure of the wideband monopulse radar, this conditional pdf is first deduced in detail for the case of compound -distributed sea clutter plus noise. Herein, the spatial correlation of the texture components for each channel clutter and the correlation of the texture components between the sum and difference channel clutters are considered, and two extreme situations for each of them are tackled. Referring to the measured sea clutter data, angle measurement performances in various K-distributed sea clutter plus noise circumstances are simulated, and the effects of compound K-distributed sea clutter on angle measurement are discussed.
