Improvement of non-linear chirp-scaling algorithm for highly squint bistatic SAR data focusing

Bistatic synthetic aperture radar (SAR) has specific advantages, e.g. weak targets detecting, reducing system vulnerability, and anti-interference with low cost and flexible working modes. However, great challenges exist in data processing procedure due to its complicated geometry and 2-D spatial va...
