摘要： A method for determining whether a target is within a direction sector of interest of a direction finder and a device for carrying out the method are disclosed. The method calls for (a) predefining the sector of interest; (b) providing at least two antennas; (c) generating an in-phase reference pattern, and establishing wireless communication between the direction finder and the target; (d) attenuating the wireless communication signal between the direction finder and the target and recording the attenuation value which corresponds to the loss of wireless communication as the R reference value; (e) generating an out-of-phase null pattern, and re-establishing wireless communication between the direction finder and the target; (f) repeat step (d) except this time recording the attenuation value which corresponds to the loss of wireless communication as the N null value; (g) determining whether the difference R−N is above or below the threshold difference.

摘要： A method for accurately tracking and communicating with a satellite from a mobile platform, wherein the satellite has an antenna which performs both transmit and receive functions from a single antenna aperture. The method involves using an inertial reference unit (IRU) of the mobile platform to initially acquire the signal from the satellite. A sequential lobing process is then used to more accurately center the antenna aperture relative to the receive beam from the satellite. The antenna is then used to transmit data or other information, and the antenna pointing is maintained by an additional IRU local to the antenna with higher accuracy and lower latency than the IRU of the mobile platform. Periodically, transmissions from the antenna are inhibited and the sequential lobing process is repeated to eliminate for any inertial reference drift error. The method allows for more accurate antenna pointing when a single antenna aperture is used for both transmit and receive functions without significantly interfering with the transmission of data or information from the antenna ( Fig. 5 ).

摘要： A space profile determining section (102) determines the distribution of strength of the received signal with respect to the direction of arrival of a signal, namely, determines the space profile or space information by using the received signal before the spectrum despreading received through antenna elements (101-1 to 101-4). An arrival direction determining section (103) determines the direction of arrival of a signal transmitted from the communication party on the basis of the determined space information and outputs the information on the arrival direction to receiving units (104-1 to 104-4) while distributing it for each direction of arrival. A beam former (111) in each of the receiving units (104-1 to 104-4) rotates the phases of the received signals outputted from the antenna elements (101-1 to 101-4) by respective predetermined angles according to the information on the arrival direction and combines the received signals so as to increase the level of the received signals received from the direction of arrival.
