摘要： A system provides a way to determine angle of bearing to a target receiver/transmitter relative to plural beacon stations with rotating directional radiation patterns. The target is “cooperative” in that it transmits a “report” message when the target receives maximum signal strength from a beacon station. Triangulation from multiple beacon transmitter sites can be used to determine the target's position.

摘要： The present invention relates to a monitoring system for land-based navigational and landing systems. A monitoring system of this type monitors the functions that are carried out by the navigational and landing system, especially the information that is transmitted to the aircraft. According to the present invention, external interfering influences that are independent of the system are detected and are taken into account in the monitoring.

摘要： An apparatus and method are disclosed for determining an aperture illumination of a phased-array antenna. The apparatus and method evaluate a monitor signal obtained from a first output (A1) of a monitor waveguide (MH). The apparatus and method are also suited for antennas having a very restricted scan angle coverage, such as elevation antennas in MLS systems. To obtain information from a portion of the monitor signal corresponding to at least one cycle of the far-field pattern of the antenna, portions of the monitor signal which are visible at different monitor angles are combined for evaluation. This is accomplished by also evaluating signals obtained from a second output (A2) of the monitor waveguide which is spatially separated from the first output (A1), or from outputs of additional monitor waveguides, at different monitor angles.

摘要： Complex modulation--that is, amplitude and phase modulation--is used to provide smaller beamwidth and better angular resolution of a scanning radio beam generated by a commutatively switched aerial. The way in which the modulation pattern may be determined is detailed, and examples are given of the application of complex modulation techniques to different types of commutative aerials.

摘要： A scanning beam radio guidance system in which a ground beacon equipment transmits a single frequency collimated beam which sweeps a space sector of interest, and also transmits a frequency offset reference signal. An airborne remote receiver is responsive to both transmissions and includes post-detection signal processing means in the form of a time gate for inhibiting those parts of the main beam signal corresponding to angles outside the sector. A filter is also included for reducing the total spectrum contribution of the residual side-lobes of any out-of-sector beam signal.

摘要： A radio-navigation station allowing, in particular, the introduction of a wide-base system in a pre-existing station with a single antenna radiating a rotating cardioid radiation pattern, without replacement of the transmitting and receiving equipment. A plurality of such antennas are used each one being successively connected, for a predetermined duration, to the receiver in the case of a direction-finding station and to the transmitter in the case of a radio-beacon.
