Abstract: The disclosed approach provides a low-cost approach by employing a single channel receiver for a direction-finding missile, rather than a conventional four-channel system. It employs interferometry techniques. The proposed approach leverages orthogonal waveforms and pseudorandom noise (PN) codes. This is a low-cost approach for a single channel direction finding system by leveraging orthogonal waveforms and interferometric techniques.

Abstract: An antenna system (10), includes a plurality of antenna elements (21–25). Respective analog signals corresponding to respective antenna elements are subjected to respective phase shifts, are digitized using one-bit samples, are then subjected to an equal and opposite phase shift, and are subsequently combined so that the fundamental components add coherently and the harmonic components add noncoherently. A digital-to-analog converter is supplied with successive samples, and produces in response to each sample a pulse having a duration which is less than the time period between successive samples.

Abstract: A digital phased array antenna comprises a plurality of antenna elements, each element receiving an incoming signal. An analog-to-digital converter is coupled to at least one of the antenna elements to convert the incoming signal to a multi-bit digital signal. A demodulator or de-ramp circuit is coupled to the analog-to-digital converter to reduce the bandwidth of the multi-bit signal.
