Effects of System Impairments on the Performance of Distributed STAP

In this paper, we study the effect of phase noise and other impairments on space-time adaptive processing. Performance of distributed space-time adaptive processing (STAP) with respect to system aspects and impairments specific to a coherent distributed system is also analyzed. The combined effects on STAP performance stemming from the distributed architecture: frequency offsets, generalized motion, sparse aperture, and sensor location errors, were also analyzed. Simulation results illustrate the effect of individual impairment and combined errors on degrading the performance of target detection.
