Abstract- This paper presents two transform do-
main non-homogeneity detectors that account for the
non-ideal array and the non-homogeneousinterference
environment. Each of these effects has been accounted
for separately before [1,2]. However, this paper is the
first attempt to incorporate both effects into a single
STAP algorithm.
The formulation developedfor the JDL algorithm is
tested on measured data from the MCARM database.
The example illustrates the effects in detection perfor-
mance by considering both the non-ideal system and
non-homogeneous interference scenario, individually
and in combination. The results show that if only
the non-homogeneousdata is accounted for, the NHD
