Estimation Accuracy of Close Approach Probability for Establishing a Radar Separation Minimum
Sakae Nagaoka, Osamu Amai · Journal of Navigation · 1991
A Long-range Secondary Surveillance Radar (LSSR) has been developed and recently used as an Oceanic Route Surveillance Radar (ORSR) in Japan. The LSSR is an SSR (Secondary Surveillance Radar) only system for which the maximum coverage is 250 nautical miles (n.m.). This system utilizes monopulse azimuth estimation techniques for improving the accuracy of azimuth estimation.
