Bistatic synthetic aperture radar (BiSAR) parametric imaging can reconstruct the structural information of target, which is one research hotspot for BiSAR imaging. However, compared with monostatic SAR, there are several challenging problems to be faced in terms imaging, such as complex echo models, compute and storage burden, azimuth-dependent phase (ADP). To this end, we first propose model, followed by analysis characteristics Based on abovementioned anaysis, a deep adaptive network...
Bistatic forward-looking spotlight synthetic aperture radar with stationary transmitter and maneuvering receiver (STMR-BFSSAR) is a promising sensor for various applications, such as the automatic navigation landing of vehicles. Because bistatic configuration receiver's maneuvers, conventional image formation algorithms suffer from high computational complexity or small size well-focused scene if applied to STMR-BFSSAR. In this article, we propose wavenumber-domain algorithm STMR-BFSSAR...
Video Synthetic Aperture Radar (SAR) has received extensive attention in recent years due to its continuous imaging capabilities. SAR requires image reconstruction, and there are many redundant operations the reconstruction process. In order meet real-time requirements of video improve data utilization, we propose a subaperture algorithm based on PFA. First, echo is divided into multiple subapertures, coarse focusing achieved respectively. Then subjected wavenumber mapping obtain...
With the rapid development of offset linear canonical transform (OLCT) in fields optics and signal processing, it is necessary to consider nonuniform sampling associated with OLCT. Nowadays, analysis applications for deterministic signals OLCT domain have been well published studied. However, none results about reconstruction random proposed until now. In this paper, are investigated. Firstly, a brief introduction fundamental knowledge some special models given. Then, theorems from samples...

Distributed MIMO Array Radars normally utilize sparse arrays with large equivalent array element spacing, which cannot avoid the generation of grating lobes that cause interference to received signal. The can be suppressed by Phase Coherence Factor (PCF) weighting factor. Regretfully, PCF has problems such as possibility suppressing main lobe well and unclear phase resolution lobes. In this paper, we propose a new factor, namely Embedded Classification (ECCF), improving an embedded...
A broadband and high-gain circularly polarized antenna based on electromagnetic band gap (EBG) structures is proposed by analyzing the influence of EBG layouts performances. Compared with reference antenna, impedance bandwidth, axial ratio bandwidth broadside gain are significantly improved. In addition, method optimizing layout provides a general strategy for designing antenna.
In the application of vehicular MIMO (Multiple Input Multiple Output) radar, it is particularly important to measure and associate position velocity targets. However, traditional methods like 3D-FFT have low angular resolution, ambiguity resolution required. Combined with Super-resolution DOA (Direction Of Arrival) algorithm, we propose a multi-dimensional information association method based on target tracking, which uses labeled GM-PHD (Gaussian Mixture Probability Hypothesis Density)...
The actual detection scenes faced by bistatic synthetic aperture radar (SAR) often have elevation information, which will cause shadow and overlay effects in imaging results.

On basis, visibility target scene can be determined obtain echo. Finally, a simulation digital...
The joint FPGA and multi-DSP imaging architecture has found widespread use in airborne SAR satellite-based SAR. However, traditional back-projection (BP) algorithms are not efficient enough for real-time imaging.
