Two atypical methods for ship RCS measurement with the laser and the acoustic wave technique

Nowadays, the measurement methods for ship radar cross section (RCS) are of many kinds, but the traditional ones exist some shortages. In view of this situation, this paper mainly presents two atypical methods for ship RCS measurements, which are respectively based on the laser and the acoustic wave technology. Using scaled theory to test the target, both of the two methods can to some certain extent make up the deficiencies of the typical ones. The former method gradually trends from theory to experiment, while the latter has formed a test system. The proposed atypical methods make a significance to the measurement of ship RCS, whether in theory or in project practice.
