Range resolution is achieved by transmitting frequency-modulated (FM) pulses, or "chirps". Phase History:
Given the high cost of the hardcover, many legitimate avenues exist to access the PDF: digital processing of synthetic aperture radar data pdf
If you want, I can:
The true distance along the Earth's surface from the ground track of the platform to the target. The Received Echo Model
If you view raw SAR data as a grayscale image, it looks like random noise or a collection of overlapping ripples. Individual targets are spread across many pixels. If you are writing or researching a paper
Synthetic Aperture Radar (SAR) is a foundational technology in modern remote sensing. Unlike optical sensors, SAR operates in the microwave spectrum. This allows it to penetrate clouds, tolerate adverse weather, and capture high-resolution imagery during both day and night.
Purchase a hardcopy for your shelf (it is a beautiful reference) and buy the legal PDF from Artech House for your tablet. Annotate the PDF. Code the algorithms line by line. Process your first RADARSAT-1 dataset. When you see that first focused image of a city or mountain range emerge from the raw noise, you will understand why this specific PDF is worth its weight in gold.
