Abstract :
A novel technique to calibrate nonlinear array of HFSWR (HF surface wave radar) by exploiting single-DOA (direction of arrival) sea echoes only is presented. It works online to supply precise channel unmatching factors in real time without interrupting regular radar operating. The technique exhibits excellent robusticity and practicability when applied to the OSMAR (ocean state monitoring and analyzing radar) HFSWR system developed by Wuhan University
