MIMO Radar Waveform Design in the Presence of Clutter

Relative Entropy-Based Waveform Design for MIMO Radar Detection in the Presence of Clutter and Interference

“…, c NT,m ] T ∈ C NT . One can obtain the following matrix model according to (1) (see [15], [22] and [24] for similar models) 2 : In what follows, we assume that h, c as well as w are mutually independent and circularly symmetric complex Gaussian random processes with (zero mean and) covariance matrices R H ∈ C NTR×NTR , R C ∈ C NTR×NTR , R W ∈ C NRL×NRL , respectively, with N TR = N T N R and N RL = N R L. We further assume a Kronecker structure for R W [21], [26], viz.…”

“…Note that R S as well as R T (and hence R W ) are full-rank due to existence of white disturbances. 1 We refer the interested reader to [15], [17], [23] [1, chapter 3], and [22] for details of the derivations of the model in (1). 2 Herein we consider ideal antenna patterns; however, the effects of the patterns can be straightforwardly incorporated in the model (see e.g., [25]).…”

“…We consider the detection performance of both statistical and colocated MIMO systems. Orthogonal waveforms are employed as the benchmark for comparisons (see e.g., [20], [22] for details/similar setups). This section also includes numerical analyses of the effects of the model mismatches on the performance of the waveforms obtained by the method.…”

Cognitive Chaotic UWB-MIMO Detect-Avoid Radar for Autonomous UAV Navigation

“…Specifically, the chaotic UWB-MIMO radar design supports significantly large degrees of freedom in choosing transmission waveform with chaotic amplitude, phase and PRI, thus imparting higher degree of freedom within waveform design and selection. As a result, chaotic UWB waveforms exhibit pronounced sensitivity to scattering relative to conventional radar signals, as shown in works [16]- [18].…”

Signal processing method of a novel polarized array radar seeker

“…The MIMO array radar system has powerful advantages in many aspects including good ability of multiple target discrimination, strong ability of saturated attack, strong ability of weak target detection, high speed resolution and so on [12][13][14][15][16]. The array radar system with MIMO is on behalf of a development direction of radar system and is studied by a lot of scholars and experts at home and abroad [17][18][19][20][21]. In this paper, both the polarization signal processing techniques and antenna array radar techniques are introduced into the radar seeker and the novel concept of the polarized array radar seeker is proposed.…”
