Abstract:

The maximum-likelihood estimate is derived of the signal correlation function under threshold conditions, where the signal is weak relative to the noise in a sense that will be defined. Such threshold conditions are to be expected in radar astronomy. Also, concentrating on the radar astronomy environment or on any environment that is characterized by a propagation medium having mutually independent, statistically stationary fluctuations at a multiplicity of delays, the maximum-likelihood estimate of the scattering function of the target is deduced.
