摘要：The -Distribution is an important clutter model for high-resolution radar sea clutter returns obtained at X-band. The Neyman-Pearson optimal multilook detector has been derived recently, as
well as the generalised likelihood ratio test suboptimal detector. Both
these detectors are dependent on the modified Bessel-function of the
second kind. This paper suggests a suitable suboptimal approach,
using a well-known Bessel identity, eliminating the Bessel function dependence. This produces a computationally simpler detection scheme,
whose performance is analysed using clutter parameters based upon
real X-band radar returns.
