Transmitter monitoring system with several antennae - switches antennae signals consecutively to transmission network and short term store, then to long term store connected to optical displays

摘要

The transmitter monitoring system uses a receiving antenna, a transmission network and an optical indicator. The receiving antenna has n individual antennas, to which n azimuth sectors are allocated. A first switch consecutively connects the n individual antennas to the transmission network. Where information is derived from the signals from the connected antenna during the monitoring interval between two switchings. This information is stored in a short-term store. A second switch distributes the information stored in the short-term store consecutively to the n inputs of a long-term store. The output signals of the long-term store control n corresponding optical indicators.
