Research on RCS measurement of ship targets based on conventional radars

Abstract A measurement method and system based on conventional radars has been proposed to address the problem of radar cross-section (RCS) ship targets in open seas. Calibration errors for RCS ground plane range (GPR) are analysed, error elimination accurate calculation formula given. An is designed by improving radars. These systems measure two Luneburg lens reflectors different sizes lake. The average big reflector obtained, calculated be 2.73% compared with its actual value, which verifies rationality system. measures a sea obtains circumferential distribution. effect ship's position results uncertainty obtained.
