Space-time adaptive processing using circular arrays

Space-Time Adaptive Processing Using Circular Arrays

A direct data-domain (D3) least-squares space-time adaptive-processing (STAP) approach is presented for adaptively enhancing signals in a non-homogeneous environment of jammers, clutter, and thermal noise, utilizing a circular antenna array. The non-homogeneous environment may consist of non-stationary clutter. The D3 approach is applied directly to the data collected by a circular antenna arra...

Space-Time Adaptive Processing Based on Unequally spaced Antenna Arrays

It is known that the spatial correlation between the desired signal and the undesired signals is an important parameter in adaptive array processing. In this paper, we consider the adaptive antenna of mobile communications under space-time adaptive processing (STAP), where user signals are of multipath rays with different delays, and the space-time correlation functions are employed instead of ...

Space-Time Adaptive Processing: Fundamentals

In this lecture, we present the principles of space-time adaptive processing (STAP) for radar, applied to moving target indication. We discuss the properties of optimum STAP, as well as problems associated with estimating the adaptive weights not encountered with spatial-only processing (i.e. beamforming).

Space-Time Adaptive Processing: Algorithms

In this lecture, we present some suboptimum STAP algorithms for radar, applied to moving target indication. In addition, we show some MTI results obtained with the multi-channel airborne experimental radar AER-II of FGAN-FHR.
