Abstract: The antenna pattern uncertainty is the main error of Synthetic Aperture Radar (SAR) system. The technique for inflight antenna pattern measurement of spaceborne SAR is one of the most important technique of SAR calibration. This paper discusses the development courses of the inflight antenna pattern measurement of spaceborne SAR, analyses its development trend and compares the main inflight antenna pattern measurement techniques. This paper will be an important reference for designing a project of inflight antenna pattern measurement of spaceborne SAR.

Location precision of radiant source is the primary performance of passive location system, and how to improve location precision is an important problem which always attracts attention. In three satellites Time Difference Of Arrival (TDOA) passive location system, location precision of single pulse location is limited by the error of TDOA measure. For improving location precision of radiant source, multi-TDOA location algorithm which estimates the position of target combining all the TDOAs is proposed in this paper. The new algorithm calculates three satellites' positions at the arrival time of each pulse firstly, and then combines all pulses' TDOA equations and earth equation, lastly estimates the position of radiant source using least square algorithm. The result of simulations shows that the new algorithm can improve location precision of radiant source, and it is a steady and effective location method with higher location precision.

This paper performs aircraft attitude/heading estimation using an airborne dipole triad antenna. The signal model is given with the parameters such as the wave Direction Of Arrival (DOA) and state of polarization. The algorithms for estimating the source DOA and electric ellipse orientation angle are presented along with their statistical performance analysis. From these parameters, the aircraft gesture angles about pitching, yawing, and rolling, which are needed by autopilot, are produced. Simulation results validate the proposed algorithm's efficacy.
