Fpgavariable Base Chirp Pulse Generator for Synthetic Aperture Radar Onboard Unmannedaerialvehicle System
نویسندگان
چکیده
Synthetic Aperture Radar (SAR) is one of active microwave sensor could work all weather and day/night time. This system can observe the objects on ground surface, and obtain microwave image by SAR image processing. SAR needs modulated signal like chirp pulse for high resolution and preciseness. In the case of UAV, some pulse parameter, i.e. bandwidth etc, should be changed to adequate value during flight or mission for stable platform posture. This paper discusses the proposed FPGA variable based chirp pulse generator to solve the platform posture effect on our UAV SAR mission.

متن کاملApply Super-SVA to SAR Imaging with Both Aperture Gaps and Bandwidth Gaps
Synthetic aperture radar (SAR) imaging usually requires echo data collected continuously pulse by pulse with certain bandwidth. However in real situation, data collection or part of signal spectrum can be interrupted due to various reasons, i.e. there will be gaps in spatial spectrum. In this case we need to find ways to fill out the resulted gaps and get image with defined resolution. In this ...

متن کاملChirp-Scaling based True Amplitude Imaging for Synthetic Aperture Radar
The Chirp-Scaling Algorithm (CSA) is one of the most widely used synthetic aperture radar (SAR) image reconstruction method. However, its applicability is limited to straight flight trajectories and monostatic SAR. We present a new mathematical treatment of the CSA from the perspective of Fourier Integral Operators theory. Our treatment leads to a chirp-scaling-based true amplitude imaging algo...
