The state-space representation for the dynamical evolution of targets and the sensor measurements is developed here using tensors in place of vectors and matrices, producing a multilinear dynamical system. In this dynamical framework, the tensor forms of the Kalman filter and the Linear Quadratic Gaussian controller are developed, allowing the simultaneous processing of (i) the inputs of all sensors, producing the estimation of the state of all agents/targets and (ii) the determination of the optimal control actions of all agents/targets. These tools are applied to implement optimal parallel waveform design and tracking control for a multi-radar system acting on multiple agents. In the study case, examined numerically, the radars can (i) estimate the state of the agents in terms of range, angular displacement, radial and angular velocities and (ii) jointly determine the agents control inputs and the radars transmitted waveforms to minimise the control cost action and the energy of the transmitted signals.</p>","PeriodicalId":50377,"journal":{"name":"Iet Radar Sonar and Navigation","volume":"19 1","pages":""},"PeriodicalIF":1.4,"publicationDate":"2025-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1049/rsn2.70056","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144681038","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Secondly, a fractional-order domain filter is constructed using the interference-free segments to conduct the primary suppression of interference in the fractional-order domain. Then, a time-frequency filter is constructed based on dechirped interference-free segments to suppress the interference again in the frequency domain. Finally, leveraging the linear relationship between frequency and distance of target in dechirped radar received signals, and the pulse compression results after interference suppression are obtained.

The need to suppress Doppler-spread clutter induced by platform motion requires the use of space–time cancellation approaches, such as displaced phase centre antenna (DPCA) or space–time adaptive processing (STAP). In particular, the recently introduced thresholded-DPCA reciprocal filter (T-DPCA-RF) was demonstrated to be especially effective in detecting moving targets within a stationary scene using OFDM waveforms on transmit. This is mostly due to the T-DPCA-RF capability to process the received signals in batches of arbitrary length, independent of the OFDM framing structure. The three-element receiving NULA design strategy for multi-channel DPCA processing proposed in this work builds upon this feature of the T-DPCA-RF. Although previous research studies have demonstrated the advantages of NULA in multi-channel DPCA, the antenna positions were chosen based on a heuristic criterion. The NULA design strategy proposed in this paper provides guidance for antenna positioning by enforcing a constraint on the DPCA filter response that prevents blind velocity effects within a specified target velocity range of interest. The effectiveness of the multi-channel DPCA detector using the NULA designed with our strategy is validated through experimental data, extending the scope of previous studies in this area.</p>","PeriodicalId":50377,"journal":{"name":"Iet Radar Sonar and Navigation","volume":"19 1","pages":""},"PeriodicalIF":1.4,"publicationDate":"2025-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1049/rsn2.70049","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144606687","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We derive the mathematical relationship between target tracking accuracy and beam allocation strategy to address this. Subsequently, we establish a beam allocation model, with the beam allocation matrix as the optimisation variable and target tracking accuracy as the optimisation objective.

In this paper, an efficient method based on reversal decoupling transform (RDT), scaled Fourier transform (SCFT) and keystone transform (KT), that is, RDT-SCFT-KT, is proposed for effective long-time coherent integration (LTCI) of an accelerated manoeuvring target with Doppler ambiguity. More specifically, an efficient RDT is performed to tackle range curvature and some other unnecessary terms. After that, the scaled inverse Fourier transform (SCIFT) and SCFT are successively introduced to handle the linear RM and DFM, thereby realising two-dimensional (2-D) energy integration. Besides, velocity and acceleration with respect to target could be acquired by the aid of peak detection. With the compensation associated with the obtained parameters, a linear and nonsearching approach involving the KT is developed to efficiently attain the final energy focusing and the remaining target parameters (i.e., range and unambiguous velocity). Given the above, the proposed RDT-SCFT-KT method could achieve LTCI for accelerated manoeuvring target and exhibits low computational complexity without requiring parameter searching process. Meanwhile, it remains effective for Doppler ambiguity (including velocity ambiguity and Doppler spectrum ambiguity) and offers complete motion parameters. Besides, the final energy integration is a linear transform process, which facilitates multi-target processing.

Track-to-track association (T2TA) of heterogeneous sensors is the precondition and foundation of heterogeneous sensor track fusion. However, problems such as ubiquitous systematic and random errors, inconsistent update periods and features caused by two heterogeneous sensors bring significant challenges to T2TA and existing methods have not solved the above problems adequately. To address these problems, we propose conditional idempotent association generation for heterogeneous track-to-track association (CIAG). In CIAG, a track state mapping module (TSMM) is constructed to unify asynchronous and heterogeneous tracks from heterogeneous sensors. The TSMM can also mitigate the effects of systematic and random errors. An idempotent association generation module (IAGM) is constructed to model tracks and association matrices jointly, and generate association matrices directly and precisely. Moreover, CIAG realises an end-to-end generation from the track tensor to the association matrix that can avoid long time consumption caused by traversal calculations of tracks.

Therefore, it is of great significance to optimise and improve this to achieve more abundant jamming effects.

The advent of deep learning techniques has significantly enhanced the efficacy of object detection and recognition systems. However, the implementation of deep networks in real-world operational settings for autonomous decision-making presents several challenges. A primary concern is the lack of transparency in deep learning algorithms, which renders their behaviour unreliable to both practitioners and the general public. Additionally, deep networks often require substantial computational resources, which may not be feasible for many compact portable platforms. This paper aims to address these challenges and promote the integration of deep object detectors in drone applications. We present a novel interpretative framework, DetDSHAP, designed to elucidate the predictions generated by the YOLOv5 detector. Furthermore, we propose utilising the contribution scores derived from our explanatory model as an innovative pruning technique for the YOLOv5 network, thereby achieving enhanced performance while minimising computational demands.
