Due to the division of transceiver, a bistatic synthetic aperture radar (SAR) gains many advantages, such as forward-looking imaging and powerful anti-interference capabilities. In meantime, information sharing (e.g., positions status) between transmitter receiver is required for SAR imaging. This article addresses co- use waveform design SAR-dual-functional communication (SAR-DFRC). To this end, we embed into time-frequency spectrum phase coded signal, which can be feasible solution...
In this article, the watermarking framework for electromagnetic systems is established with nonblind, semiblind, and blind demodulation processes mitigated to applications like radar detection, synchronization, integrated dual function, etc. Desired similar advantages trade-offs of technology, function communication (DFRC) system specifically concerned covert low possibility interception (LPI) sensing. respect, we propose a novel DFRC waveform design method where peak sidelobe level (PSL)...
High sidelobe of strong scattering points usually submerges weak targets nearby and affects the quality SAR image. Therefore, image requires control. Common window functions have limited improvement on PSLR performance when resolution is required to be guaranteed. Combining Min-Max weighted ISL technique, this paper proposes an azimuth low function design method for SAR. Simulation results show that designed nearly −10dB lower than hanning with a −45dB level, main lobe width almost equal window.
The clutter background poses a challenge to the detection and recognition of targets from synthetic aperture radar (SAR) images, especially when target is submerged by clutter. In this paper, we propose target-oriented SAR waveform optimization method deal with problem. proposed constructs an criterion jointing signal-to-clutter ratio (SCR) resolution transmitted waveform. Based on prior information frequency response interested target, suppression performance range are jointly optimized....
