Angular Resolution Beyond the Rayleigh Limit

摘要

The problem of angular resolution is formulated in a statistical decision theoretic context. A tutorial discussion of decision theory and its application to resolution is presented, and an explicit signal processing radar system is derived whose resolving properties approach an optimum. Computer simulation tests show that the system is capable of reliably resolving targets as close as a quarter of a 3-db beamwidth in the presence of noise and system errors. (Author)
