Abstract

The measurements of the two closely-spaced targets will be merged when the target echoes are not resolved in angle, range, or radial velocity. The modified Cramer Rao lower bound (CRLB) is given for monopulse direction-of-arrival (DOA) estimation for two unresolved Rayleigh targets and used to give insight into the antenna boresight pointing. A monopulse processing technique is given for DOA estimation of two unresolved Rayleigh targets. The Nearest Neighbor Joint Probabilistic Data Association Algorithm is extended to include the possibility of merged monopulse measurements of Rayleigh targets. The monopulse signals are incorporated into the data association as a feature to discriminate between merged and resolved measurements.
