Nonuniform Grid Fast Factorized Backprojection for Multimode SAR Processing

Conventional fast factorized backprojection (FFBP) algorithms for synthetic aperture radar (SAR) modes such as stripmap, sliding spotlight, and TOPS suffer from oversampling redundancy in partially illuminated regions due to the use of uniform azimuth grids, which limits computational efficiency. This article proposes...

Frequency-Domain Decoupling and Subband Synthesis-Based Adaptive Monopulse for Distributed Coherent Aperture Radar in Multidirectional Jamming

Due to the long baselines and sparse aperture structures of distributed coherent aperture radars, jamming signals from multiple directions exhibit a dispersion phenomenon, where the steering vectors depend on both angle and frequency. This significantly complicates interference suppression and impairs the accuracy of s...

Maneuvering Targets Fusion Filtering for Vehicle-Mounted Multisource Heterogeneous Sensor Using MHS-GRU-Fusion Net

Autonomous driving requires environmental perception and target tracking with vehicle-mounted heterogeneous sensors. The data from those devices demand fusion and filtering techniques, operations which are challenged by a lack of proper solutions for model and time mismatches. Traditional target tracking methods based...
