Bistatic motion compensation

WebBistatic SAR motion compensation. Bistatic SAR systems require phase stability values that are typically 1/10th to 1/100th of a wavelength, corresponding to 0.01 to 0.001 ft of displacement at X-band. The transmitter and receiver can be separated by very long distances requiring phase locking, requiring the phase locking of the two units and ... WebSAR motion compensation can be divided into two parts: motion compensation based on motion-sensing information and motion compensation based on echo data. The …
