Abstract

Monostatic and bistatic Synthetic Aperture Radar (SAR) imaging systems with Wide-Bandwidth Continuous-Wave (WB-CW) sources have been utilized for military reconnaissance. WB-CW sources are less susceptible than FM-CW sources to Electronic Counter Measures (ECM). The main shortcoming of the WB-CW microwave illumination is that its resultant SAR echoed signal is not composed of distinct Doppler spreading around specific tones; this creates difficulties to formulate the image formation in the WB-CW SAR systems via the conventional pulse or FM-CW SAR imaging algorithms. The current paper outlines a Time Domain Correlation (TDC) processing method and a Fourier-based processing method for image formation in WB-CW monostatic and bistatic SAR systems. Results are provided.
