Digital Processing of Synthetic Aperture Radar Data: Algorithms and Implementation

Active microwave remote sensing has revolutionized earth observation. Unlike optical sensors, SAR systems actively transmit microwave pulses and measure the backscattered energy. The challenge in SAR lies in processing the phase history of the returned signals to achieve high resolution in both the range (cross-track) and azimuth (along-track) directions. Digital processing is required to handle the massive data volumes and complex arithmetic operations necessary to focus the image. digital processing of synthetic aperture radar data pdf

3. Processing Pipeline

• Input: Raw data matrix (Range lines x Azimuth lines).
• Operation: Fast Fourier Transform (FFT) in the range direction.
• Process: Multiply by the range matched filter reference function.
• Output: Range-compressed data. Targets appear as distinct impulses in range but remain smeared in azimuth.
