Efficient space-time adaptive processing for airborne MTI-mode radar

Abstract: Space-time adaptive array processing has emerged as a key technology thrust area for the next generation of airborne radar systems due t o its inherent potential for vastly improving moving target indicator (MTI) performance. Unfortunately, these performance gains come with a commensurate increase in on-line computational complexity if full degree-of-freedom (DOF) STAP processors are employed. In this paper we introduce a class of efficient STAP processors which exploit the fact that the full DOF space-time cl… Show more

“…Consider a ULA consisting of J channels spaced equally at d meters apart. A CPI for this system will consist of data collected over K slow time pulses with a sampling period of T seconds and L fast time range bins 1 . We shall assume that the system is narrowband, i.e., the 1 Slow time refers to the relatively long intervals between successive pulses from a coherent radar.…”

We shall assume that the system is narrowband, i.e., the 1 Slow time refers to the relatively long intervals between successive pulses from a coherent radar. Fast time refers to the time scale at which the electromagnetic pulse travels across the scene of interest, which is the same as range up to a scale factor.…”

“…The clutter is generated near the target zone, and the existence of a wideband Gaussian-distributed barrage-jammer is introduced. For clutter and jammer suppression, the sample matrix inversion (SMI) method has been used; this includes the clutter and jammer covariance matrix with the subspace-based Digital BeamForming (DBF) algorithm (Guerci, 2013). The DBF algorithm is employed to cover a detection area of a long range (2000 m) and an angular orientation of [90 o , 35.26 o ] with respect to the RADAR platform flying in an airplane under the airborne scenario.…”
