The exploitation of the finer resolution and wider coverage of these geometries has been shown to reduce the often-impractical data collection requirements of 3D SAR imagery; this offers advantages such as improved target identification and the removal of layover artefacts. This paper presents a novel polarimetric generalisation of the SSARVI algorithm, which was previously developed to exploit sparse aperture multistatic collections for 3D SAR image formation. The new algorithm presented here, named the PolSSARVI algorithm, combines polarimetrically weighted interferograms for determining the 3D scatterer locations from sparse aperture polarimetric collections. The bistatic generalised Huynen fork polarimetric parameters are then determined for the multistatic PolSSARVI 3D SAR renderings. This new approach was tested on both simulated and experimental data.

Recognising an MFR's operating mode is critical in electronic warfare and intelligence reconnaissance, aiding practical threat assessment and countermeasure tasks. However, current recognition methods face challenges such as overlapping parameters among working modes and suboptimal recognition accuracy under conditions with parameter errors, missing pulses and false pulses. Spurred by these concerns, this paper proposes an entropy-enhanced spatial-deformable hybrid multiscale group network (E-SDHGN) to recognise the operating mode of an MFR and address these challenges. E-SDHGN employs multidimensional entropy computations to construct robust features and integrates deformable convolution and positional encoding to enhance the model's ability to capture complex features. Additionally, it enhances feature extraction and fusion within the dynamic shared residual network (DSRN) module by integrating KAN modules and hybrid weight-sharing strategies. Additionally, an adaptive margin feature module based on attention mechanisms improves classification accuracy in overlapping parameter conditions. Experimental results demonstrate that E-SDHGN achieves superior recognition accuracy and robustness, even under challenging parameter errors, missing pulses and false pulses. This underscores its value for applications in complex electromagnetic environments.</p>","PeriodicalId":50377,"journal":{"name":"Iet Radar Sonar and Navigation","volume":"19 1","pages":""},"PeriodicalIF":1.4,"publicationDate":"2025-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1049/rsn2.70025","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143801705","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}

There are several indicators for a drone's intent, for example, its size, payload and behaviour. In this paper, a method is proposed to estimate two or more of the following four indicators: a drone's wing type, its number of rotors, the presence of a payload and its mean rotor rotation rate. Specifically, three multitask learning (MTL) approaches are analysed for the simultaneous estimation of several of these indicators based on radar micro-Doppler spectrograms. MTL refers to training neural networks simultaneously for multiple related tasks. The assumption is that if tasks share features between them, an MTL model is easier to train and has improved generalisation capabilities as compared to separately trained single-task neural networks. The proposed MTL approaches are validated with experimental data and in a variety of combined classification and regression tasks. The results show that MTL approaches can provide improvement in several tasks compared with conventional approaches.</p>","PeriodicalId":50377,"journal":{"name":"Iet Radar Sonar and Navigation","volume":"19 1","pages":""},"PeriodicalIF":1.4,"publicationDate":"2025-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1049/rsn2.70012","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143778420","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}

In the present investigation, a similar transmitter-receiver antenna system is developed for which the collected power of a linearly polarised receiver antenna depends only on the spherical radial distance from a specially designed transmission antenna to this receiver antenna and is independent of the spherical angular coordinates. This system design capitalises on the radiative properties of a particular spherical transmission antenna that is characterised by azimuthal rotation of the radiative fields and power pattern. This property of 3D isotropic power reception applies exactly in the near field, far field and all intermediate ranges from the spherical transmitter to the linearly polarised receiver. Likewise, this 3D isotropic receive power property is applicable for all radio frequency (RF) wavelengths, both larger and smaller than the radius of the spherical transmission antenna.

Aiming at the scene where radar detects and tracks targets, this paper proposes an optimisation method of a radar intelligent game anti-jamming strategy based on the inference and induction of jamming behaviour with an OODA (observation, orientation, decision and action) loop. Firstly, the strategy selection of the OODA loop decision process of the jammer is optimised so that the jammer can predict radar behaviour. Secondly, the radar is given the ability to perceive the jammer strategy and infer the decision-making ability of the jammer, and the radar behaviour with inductive ability is selected to generate the cover pulse so that the radar can recover the detection in time under the disadvantage situation, and the OODA loop cycle speed is improved under the advantage situation.

This paper provides a number of techniques for manipulating the shape of radar ambiguity functions. A new and simple characterisation of the radar ambiguity function is introduced in terms of twisted convolution. It is shown that the ambiguity function of any waveform can be transformed by any desired area preserving linear transformation of the delay-Doppler plane. Furthermore, given the desired delay-Doppler transformation, the corresponding waveform transformation can be explicitly constructed through the factorisation of <span></span><math>\u0000 <semantics>\u0000 <mrow>\u0000 <mn>2</mn>\u0000 <mo>×</mo>\u0000 <mn>2</mn>\u0000 </mrow>\u0000 <annotation> $2times 2$</annotation>\u0000 </semantics></math> matrices. Among other applications of this theory, it is shown that the usual OTHR phase and frequency coding techniques used for range-folded spread Doppler clutter mitigation, which induce an approximate Doppler shearing of delay-Doppler plane, can be replaced by chirp modulating the recurrent waveform.

Among the existing methods, <i>received signal strength indicator</i> (RSSI)-based localisation is widely used due to its low cost and simplicity. However, most RSSI-based techniques make simplifying assumptions, such as relying on basic path-loss models and presuming the emitter has already been detected, overlooking complex environmental effects like shadowing caused by obstacles. These limitations hinder the practical application of RSSI-based methods. In this paper, we propose an advanced RSSI-based framework for <i>joint detection and tracking</i> (JDT) of a radio emitter, integrating a more accurate propagation model that accounts for both path-loss and shadowing effects. The emitter is modelled as a Bernoulli <i>random finite set</i> (RFS) characterised by its <i>existence probability</i> (EP) and <i>spatial probability density function</i> (SPDF), addressing the challenges of emitter detection uncertainty. A key innovation of this paper is the development of a fully distributed JDT algorithm, which overcomes the computational and communication challenges associated with centralised tracking systems. The proposed algorithm leverages <i>parallel consensus on likelihood and prediction</i> (PCLP), allowing for scalable and efficient operation across sensor networks.

To address systematic errors that remain constant over short periods—such as those introduced by the spacecraft's measurement instruments and satellite systems—these constant errors are incorporated into the state model to improve estimation and prediction accuracy. Moreover, to further enhance navigation precision, the approach integrates x-ray pulsar navigation, inter-satellite ranging, and landmark-based navigation thereby improving system robustness.
