The proposed algorithm is based on the principle of block majorization minimization (block MM) which is a combination of block coordinate descent and majorization-minimization (MM) methods.

The proposed method can additionally handle the cases where the transmitter also acts as a receiver. The framework can also be applied to the case of non-uniform noise variances at the receivers. Several numerical simulation results are included to show the benefits offered by the developed design algorithm.","PeriodicalId":100645,"journal":{"name":"IEEE Transactions on Radar Systems","volume":"2 ","pages":"391-403"},"PeriodicalIF":0.0,"publicationDate":"2024-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140537399","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Radar altimeter (RA) is well suited to provide precise height Above Ground Level (AGL) under the worst environmental conditions viz engine plumes, dust, cloud-covers, etc. The problem of precise nadir altitude estimation using a single RA system configuration under a wide range and attitude variation of ±25° is a challenging and open issue. The wide antenna beam is necessary to get adequate return power from the ground to measure the altitude under the influence of a wide range of attitude variations. Under the circumstances, the major problem of the existing methods for long-range measurement along with wide attitude variation is that they easily lose the current altitude value or require a long tracking time. This paper presents the design of a novel robust RA-processing algorithm, the design and implementation of high-performance processors, architecture details, and salient performance features. This digital Radar Altimeter’s high throughput processor performance has been validated via extensive lab tests and field tests and achieved excellent performance during the actual Landing of ISRO’s autonomous Re-usable Launch Vehicle (RLV) mission under wide attitude variation.","PeriodicalId":100645,"journal":{"name":"IEEE Transactions on Radar Systems","volume":"2 ","pages":"372-379"},"PeriodicalIF":0.0,"publicationDate":"2024-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140297130","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Specifically, we build the FDA-MIMO receive signal model by capitalizing on orthogonality in the frequency domain. Subsequently, an inverse complex Wishart distribution is assigned to the clutter covariance matrix for mathematical tractability, serving as knowledge-aided information. With free training data, two adaptive detectors are introduced by leveraging the Bayesian framework, based on Rao and Wald criteria, namely, Bayesian Rao (BRao) and Bayesian Wald (BWald), respectively. Notably, it is essential to highlight that the received FDA-MIMO signals can be directly applied to adaptive detectors without needing matched filtering. The simulation results confirm that, in the case of signal matching, the BWald can provide detection performance comparable to that of the existing BGLRT. Additionally, when facing mismatched signals, the proposed BWald and BRao detectors demonstrate stronger robustness and selectivity capabilities.","PeriodicalId":100645,"journal":{"name":"IEEE Transactions on Radar Systems","volume":"2 ","pages":"344-354"},"PeriodicalIF":0.0,"publicationDate":"2024-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140192050","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this scenario, multiple distributed transmitters emit signals received by two-channel distributed receivers, with one channel for surveillance and the other for reference. To address this PR detection problem, we propose two detectors based on the likelihood ratio test (LRT) principle. One is a subspace-based detector, where the unknown interference subspace is estimated. In this detector, only surveillance channels (SCs) are used to formulate the detection problem as a binary composite hypothesis-testing problem. However, reference channels (RCs) are employed to estimate the unknown interference subspace, resulting in a two-step detection method with a single-channel formulation. The second detector is an eigenvalue-based detector that utilizes both SCs and RCs to formulate the target detection problem. In addition, we present a low-complexity implementation of the eigenvalue-based detector, making it suitable for short- to long-range PR scenarios. Simulation results demonstrate the effectiveness of the proposed detector in target detection and interference cancellation capabilities.","PeriodicalId":100645,"journal":{"name":"IEEE Transactions on Radar Systems","volume":"2 ","pages":"549-560"},"PeriodicalIF":0.0,"publicationDate":"2024-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141308634","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

FDA-MIMO radars enjoy the advantage of range-angle-dependent beampattern, which can be used to resolve closely spaced targets and estimate their parameters. To this end, classical subspace methods are not efficient enough, specifically when working with a limited number of snapshots. In this article, a computationally efficient, compressed sensing (CS)-based method is proposed to jointly estimate incremental-range, angle, and Doppler frequency of the targets in FDA-MIMO radars. The proposed method is called 3-D decoupled atomic norm minimization (3D-DANM). It transforms the estimation problem into a semi-definite programming (SDP) problem. The range, angle, and Doppler frequency of the targets are extracted by the Vandermonde decomposition of the Toeplitz matrices resulting from the SDP problem. The extracted parameters are then paired using a specific approach. Based on the simulation results, the performance of the proposed method attains the Cramér-Rao lower bound (CRLB) for sufficient signal-to-noise ratio (SNR) values.

However, detecting small targets on the sea surface is a challenging task for marine surveillance radars because of the weak echoes and relatively low velocity. While there is a similarity and significant body of research on high-resolution radar sensing in the automotive environment, the direct translation of such techniques to marine sensing is difficult due to the fundamentally dynamic underlaying sea surface. This article addresses the need of developing novel radar sensing capabilities to image and, potentially, classify small marine targets, such as paddlers, buoys, flotsam and jetsam, or the incoming large waves. Our proposed approach combines multiple-input–multiple-output (MIMO) and Doppler beam sharpening (DBS) beamforming techniques with the ordered statistics cell averaging constant false alarm rate (OSCA-CFAR) for robust target detection, density-based spatial clustering of applications with noise (DBSCAN) for clustering, and an adaptive focusing technique.
