WebJul 26, 2024 · The chirp scaling operation slightly increases the chirp rate of all signals and adds a linear phase that increases with target distance from the scene centre. In the subsequent matched filtering operation, this linear phase component shifts the range location of a point target response nearer to scene centre. The size of this shift increases ... WebJan 1, 2004 · Abstract and Figures. Non-Linear Chirp Scaling is an innovative way to focus bistatic SAR images and has been demonstrated to work on the configuration where the transmitter imaging on broadside ... crystal ball alternative
