A Two-Stage STAP Method Based on Fine Doppler Localization and Sparse Bayesian Learning in the Presence of Arbitrary Array Errors [PDF]

open access: yesSensors, 2021
In the presence of unknown array errors, sparse recovery based space-time adaptive processing (SR-STAP) methods usually directly use the ideal spatial steering vectors without array errors to construct the space-time dictionary; thus, the steering vector

Comparison of the performance of adaptive space-time processing against the background of alternative methods [PDF]

open access: yesBiuletyn Wojskowej Akademii Technicznej, 2020
Description and successive stages of the STAP algorithm were characterized in this article. The ability to detect an object by using 6-element antenna array without space-time processing and using the STAP technique were compared and shown.

Two-Step Low-Complexity Space-Time Adaptive Processing (STAP) [PDF]

open access: yes2010 IEEE Global Telecommunications Conference GLOBECOM 2010, 2010
This work proposes a low-complexity space-time adaptive processing (STAP) algorithm for sensing applications built on a moving platform in the presence of strong clutters. The proposed algorithm achieves low-complexity computation via two steps. First, it utilizes improved fast approximated power iteration methods to compress the data into a much ...

Polarisation-space-time adaptive processing for heterogeneous clutter suppression of airborne-phased array radar

open access: yesThe Journal of Engineering, 2019
Conventional space-time adaptive processing (STAP) achieves clutter suppression by combining spatial signals and the temporal pulses. However, extreme slow-moving target cannot be effectively detected by space-time joint filtering in ambiguous and non ...

Robust Multiple-Measurement Sparsity-Aware STAP with Bayesian Variational Autoencoder

open access: yesRemote Sensing, 2022
Due to the shortage of independent and identically distributed (i.i.d.) training samples, space−time adaptive processing (STAP) often suffers remarkable performance degradation in the heterogeneous clutter environment.
