50271261, Jun 25, 1991

Filed:

May 17, 1989

Appl. No.:

7/353298

Inventors:

Mohammad Mazooji - Santa Barbara CA

Assignee:

Raytheon Company - Lexington MA

International Classification:

H01Q 322

US Classification:

342372

Abstract:

A beam steering module for rapidly applying control signals to a plurality of digital phase shifters in a phased array antenna system. The module can receive and store a plurality of phase shift commands for a plurality of phase shifters. The commands may be quickly applied to the phase shifters to rapidly steer the beam from the antenna array.

International Classification:

H04B 1700

US Classification:

4552264

Abstract:

A circuit to improve the sensitivity of a receiver by more than 3 dB. According to the invention, conventional predetection integrators are replaced by a circuit to compute the correlation of the received signal with a delayed version of the received signal. The time delay is selected such that the noise in the signal and the delayed signal are statistically independent.

US Classification:

342169

Abstract:

A low cost simulator for training electronic warfare operators to recognize signatures of various emitters. The simulator consists of a card which can be plugged into an IBM PC or compatible computer. Through the computer, various characteristics of one, or a plurality of emitters are entered. The simulator, using an existing digital signal processing (DSP) chip generates a replica of a signal received by a radar system receiver from one, or a plurality of emitters.
