Russian decametric-wave instrument landing surface equipment

Abstract

The invention relates to Russian decametric-wave instrument landing surface equipment. The equipment is composed of a localizer and a glide slope, wherein the localizer comprises a ranging / locating engine, a locating antenna, a locating out-field detection device and a ranging antenna; the glide slope comprises a glide engine, a glide antenna, a glide out-field detection device and a glide mixed unit; a unit circuit board in the engine adopts a fast plugging mounting mode; and a radio frequency (RF) unit comprises a locating transmitter, a glide transmitter, a ranging transmitter, a ranging receiver and a duplexer, wherein a BMA blind plug is used for the RF connection of the RF unit and is plugged into the engine directly to achieve the RF connection. The equipment has the advantages that the equipment is combined with microwave landing equipment to achieve co-location mounting combination use, the generality of the equipment is high, the maintainability and the testability are good, and the equipment is provided with remote control and computer maintenance functions.

Description

technical field [0001] The invention relates to instrument landing equipment, in particular to a new type of Russian-made decimeter wave instrument landing ground equipment. Background technique [0002] At present, the new Russian-made decimeter wave instrument landing ground equipment is the instrument landing equipment of the Russian system, which is used to provide accurate radio landing guidance signals for Russian-made aircraft such as Su-27 and Su-30, and is a supporting tool for ensuring the safe landing of Russian-made aircraft The advanced ground radio navigation equipment can be used as a type I or type II landing system, commonly known as "Russian blind landing" or "Russian blind". The deficiencies of the existing Russian-made decimeter wave instrument landing ground equipment include 1, there is no remote control function. 2. Low testability; system monitoring is not perfect, and some basic parameters such as frequency are not monitored; there is no dat...
