ABSTRACT:
A transmit/receive system for electromagnetic radiation, particularly radar, employs an array of active transmit/receive (T/R) modules. Only a portion of the modules are actuated to transmit or receive signals at any given time. Input transmit power is supplied to all modules, but only the selected portion of modules actually amplify their inputs. The power loss is thus kept small because the amplified signal power far outweighs the lost input power. This approach makes possible a monopulse signal routing scheme that minimizes the number of switches used and their accompanying reliability problems. Transmit and receive signals are routed through sum-and-difference circuits and respective sectors of the T/R modules such that during RECEIVE no switches are necessary to acquire a monopulse sum (.SIGMA.) signal, and only a single switch is required to acquire a monopulse difference (.DELTA.) signal. Similarly, no switching of module inputs is required during TRANSMIT.
