“…These algorithms are divided into two major groups: (1) Time-domain algorithms: such as Backprojection (BP) and Time-Domain Correlation (TDC) algorithms and (2) Frequency-domain algorithms: such as, Range Stacking algorithm (RSA), Polar Format Algorithm (PFA), Frequency scaling algorithm (FSA), Range Doppler algorithm (RDA), range migration algorithm (RMA), and Chirp Scaling algorithm (CSA). (Okoń-Fąfara et al, 2016;Yigit et al, 2013) compared the performance of time-domain and frequency-domain algorithms in FMCW SAR systems. (Reigber et al, 2013) Reviewed signal processing and imaging algorithms for very high-resolution SAR systems including time-domain algorithms, frequency-domain algorithms, and error correction methods.…”

Synthetic aperture radar (SAR) system based on frequency modulated continuous wave (FM-CW) transmission is a viable option for producing high-resolution ground-based imaging radars. Compared with pulsed SAR systems, the combination of FM-CW technology and SAR processing techniques have the advantages of small cubage, lightweight, cost-effectiveness, and high resolution in the SAR image. These characteristics make FM-CW SAR suitable to be deployed as payload on ground Based SARs (GB-SARs) for environmental and civilian applications. In this paper, the Range Migration Algorithm (RMA) is used in the processing chain of a Ground-Based SAR (GB-SAR) sensor. The mentioned sensor has been developed in Microwave Remote Sensing Laboratory (MReSL) at the School of Surveying and Geospatial Engineering, the University of Tehran for the generation of a complex image from the raw signal. The raw signal is acquired with that sensor working at S-band, frequency modulating from 2.26 GHz to 2.59 GHz.
