Abstract

A method and apparatus for detecting a short pulse signal in the presence of an interfering jamming signal wherein the jamming signal is utilized as the local oscillator in a diode mixer when it is received at a sufficiently high level for efficiently mixing with a short pulse signal. When the received jamming level is insufficient to act as a local oscillator, an internal local oscillator signal is coupled to the diode to maintain an efficient mixing operation.
