Abstract

One of the modern issues in SAR processing is the use of the OFDM waveform instead of the conventional LFM signal. OFDM is a digital modulation scheme in which some orthogonal sub carriers are used simultaneously dividing the available bandwidth into several narrowband and parallel sub channels. The advantages of using OFDM waveform for synthetic Aperture radar (SAR) imaging include enhanced resistance against jamming, lower Doppler ambiguity and the possibility of extracting phase background of the target on the basis of phase estimation of the OFDM sub carriers. In this paper, the basic relations of OFDM waveform generation was reviewed firstly, and then the form of imaging in the range and azimuth by using this signal in the form of RDA ALGORITHM was described.
