Abstract

It is difficult to form an narrow beam on elevation in the high frequency band. As a result, high frequency surface wave radar(HFSWR) is traditionally unable to detect the target altitude information. Under the bistatic T/R-R HFSWR configuration, an altitude and radar cross sections(RCS) estimation model is proposed with the target echo amplitude information. With four measurement vectors, centralized fusion estimation is adopted to improve the estimation accuracy of target altitude and RCS. Geometrical Dilution of Precision(GDOP) of altitude and the drawbacks of geometric method are also analyzed. Simulations demonstrate the effectiveness of the presented estimation model.
