We derive the nonhomogeneity detector (NHD) for non- |
|
Gaussian interference scenarios and present a statistical |
|
analysis of the method. The non-Gaussian interference |
|
scenario is assumed to be modeled by a spherically |
|
invariant random process (SIRP). We present a method for |
|
selecting representative (homogeneous) training data |
|
based on our statistical analysis of the NHD for finite |
|
sample support used in covariance estimation. In |
|
particular, an exact theoretical expression for the NHD |
|
test statistic probability density function (PDF) is |
|
derived. Performance analysis of the NHD is presented |
|
using both simulated data and measured data from the |
|
multichannel airborne radar measurement (MCARM) program. |
|
A performance comparison with existing NHD approaches is |
|
also included. |
