The present invention relates to multi-function, multi-channel digital receiver architecture for performing three distinct receiver functions including simultaneous intrapulse analysis, direction finding and LPI signal detection; for determining parameters of incoming signals, comprising a plurality of receiver channels, each channel including a respective antenna for receiving the signal; a down-converter for converting the signal to an intermediate frequency (IF) signal; and an analog-to-digital converter operatively coupled to receive the IF signal and to provide a digital signal at a sampling rate, the digital signal being indicative of the amplitude and phase of the received signal in the channel, and a digital processor operatively coupled to receiving the digital signals from each of the plurality of channels for determining the amplitude and phase intrapulse profiles; by combining the amplitude and phase intrapulse profiles from all of the plurality of channels to provide both intrapulse and conventional parameters of a better quality on a pulse by pulse basis; and utilizing both the AOA and intrapulse information for parameter validation under multipath conditions.
