In this paper, we propose novel l<sub>1</sub>-regularized space-time adaptive processing (STAP) algorithms with a generalized sidelobe canceler architecture for airborne radar applications. The proposed methods suppose that a number of samples at the output of the blocking process are not needed for sidelobe canceling, which leads to the sparsity of the(More)
This paper derives the extended ambiguity function for a bistatic multiple-input multiple-output (MIMO) radar system, which includes the whole radar system parameters: geometric sensor configuration, waveforms, range, range rate, target scattering and noise characteristics. Recent research indicates the potential parameter estimate performance of bistatic(More)
In this paper, we propose a new l<inf>1</inf> regularized space-time adaptive processing (STAP) technique with a generalized sidelobe canceler (GSC) architecture for airborne phased-array radar applications. The core idea of the proposed method is imposing a sparse regularization (l<inf>1</inf>-norm) to the minimum mean-square error (MMSE) criterion. By(More)
This paper proposes a compressive space-time adaptive processing (CSTAP) airborne radar by reducing the samples in one coherence processing interval with random pulse repetition interval and random arrays, termed as the RPRI-RA radar. We firstly detail the compressive sampling in spatial and Doppler domain and develop a rule for the clutter rank estimation(More)
Coincidence imaging radar (CIR) can achieve super-resolution in real aperture staring radar imagery by employing temporal-spatial independent array detecting (TSIAD) signals. The characteristics of TSIAD signals are determined by the random signal waveform and the array geometry, and the imaging performance is influenced by the relative imaging position(More)
In this paper, we address the design of optimal waveform for detecting extended target in signal-dependent interference. A two-step waveform design algorithm is proposed to obtain the optimal phase-modulated (PM) waveform with constant modulus. We first obtain the normally called water-filling waveform in frequency domain and subsequently synthesize the(More)
