    摘要: An active array system with electronic roll stabilization of the difference patterns, and with arbitrary partitioning of the phase scanned aperture with no hardware changes. The array system comprises a large number of radiating elements forming the array, with individual transmit/receive active modules coupled to each radiating element. In each active module, the received signal is amplified and then divided (164) into three signal components. Two of the signal components are passed through a bi-state phase shifter (166, 168) for selectively phase shifting the signal component by 0 to 180 degrees. The selectively phase shifted receive signals are then coupled to the respective azimuth and elevation difference channels (92, 93). The third signal component is coupled to the sum channel (91) network. The respective sum and difference channels all provide summing functions on the respective sum and differnce signals from each module. The phase shifters provide an output signal with either a positive or negative sign, so that in effect the module signals are ''differenced'' first and then summed.

    摘要: A robust antenna tracking system apparatus (10) is capable of quickly and accurately tracking satellites without the use of a compass under adverse conditions while being subjected to large torque stress and being weatherproof. The apparatus can be attached to a ship or land vehicle and can be used while the vehicle is in motion. Upon the customer choosing a satellite from which to receive signals (202), the invention acquires a satellite by scanning the sky to locate a system labeled primary satellite (204). The identification of the system labeled primary satellite is accomplished by comparing the leading and falling edges of rf-signal pulse (220a), comparing beacon signal transmissions (220b), comparing the relative positioning of other satellites (220c), or determining the angle of elevation of the satellite relative to the horizon (220d). Upon identifying the system labeled primary satellite, the customer chosen satellite is located by calculating its position relative to the system labeled primary satellite (300, 302), and then verifying (306) the customer chosen satellite through on the four identifying means used for the system labeled primary satellite (220a, 220b, 220c and 220d). Satellites are tracked by measuring the increase and decrease in signal strength (308, 310a and 310b) as the antenna is moved a known distance within the satellite's range.
