TITLE: Adaptive UWB-OFDM Synthetic Aperture Radar | |
Abstract—
This paper presents an empirical study of high resolution potentially jamming-resistant Synthetic Aperture
Radar (SAR) system based on UWB-OFDM architecture. The Range-Doppler Algorithm (RDA) was used to construct a high
resolution SAR image for simulation purpose. Suitable waveforms to achieve high resolution SAR imaging are proposed for both friendly and hostile environments. The proposed waveforms were tested for a point scatterer and for full 2-D SAR image construction. Simulation results demonstrate the benefits of using UWB-OFDM waveforms for SAR system, such as dynamic spectrum allocation, anti-
jamming potential through pulse diversity-while having a potential to produce high resolution target images. The use of UWB-OFDM waveform for SAR system proves useful for high resolution image data collection for civilian purposes and provides significant anti-jamming capabilities for military
purposes.
