Iterativer Ansatz zum Erzielen einer Winkelmehrdeutigkeitsauflösung

摘要

Realized in a kind of two-dimensional Doppler polarization sensitive synthetic aperture radar system angular ambiguity resolution a kind of system and method include transmission using multiple pulses on it a platform of installation system mobile period transmission element. It is reflected from pulse from an objective result, and reflects to be processed into and determine a Doppler measurement. Processing includes the movement for the target being isolated in Doppler measurement, determine the target bearing angle and a target elevation angle of the target base in an iterative process comprising estimation target elevation angle or target bearing angle are then based on a beam shape matrix and determine target bearing angle or target elevation angle respectively. Beam shape matrix indicates the amplitude and phase at each azimuth and each elevation angle among one group of azimuth and one group of elevation angle.
