A launcher for a surface surveillance radar system

Abstract

The invention belongs to the field of radar electronic communication, and particularly relates to a transmitting device of a scene surveillance radar system. The transmitting device comprises a box-shaped housing and an upper cover board for closing the box opening of the housing. The box chamber of the housing forms an accommodating chamber for accommodating components. The components at least comprise a waveguide synthesizer, a coupler and a filter, wherein the waveguide synthesizer, the coupler and the filter are successively arranged in an engaging manner. The adjacent matching surfaces of the waveguide synthesizer, the coupler and the filter are flange surfaces and form a fixed flange fit. A shielding sealing ring which is used for improving electromagnetic shielding capability is embedded into each flange surface. The transmitting device has advantages of improving assembling and maintenance efficiency of the device, and effectively reducing or even preventing leakage of microwave signals. The transmitting device has advantages of high structure compactness, smaller device size, and effective improvement of convenience in maintenance.

Description

technical field [0001] The invention belongs to the field of radar electronic communication, and in particular relates to a launcher for a surface surveillance radar system. Background technique [0002] Surface surveillance radars are generally installed on airport towers to monitor targets such as aircraft and vehicles within the near-ground range and extract information such as distance and azimuth of targets. They have the advantages of high positioning accuracy, fast data refresh rate, and high reliability. In the above-mentioned field surveillance radar products, the transmitter structure as the signal transmitting element is very important. The current design defects of the above-mentioned transmitter structure are as follows: First, due to the large number of high-power components inside the structure, the current transmitter has many The use of fan air cooling not only leads to poor cooling effect, but also may increase thermal resistance, resulting in reduced heat ...

Problems solved by technology

In the above-mentioned field surveillance radar products, the transmitter structure as the signal transmitting element is very important. The current design defects of the above-mentioned transmitter structure are as follows: First, due to the large number of high-power components inside the structure, the current transmitter has many The fan cooling method not only leads to poor cooling effect, but also may increase thermal resistance, resulting in reduced heat transfer efficiency

Second, traditional transmitters mostly use cable connection to ensure the electrical connection and signal transmission between internal components, especially for the RF output part of the signal, which is very prone to leakage of microwave signals

At the same time, due to the messy cable connection methods between various components, it is necessary to have a very high resolution efficiency for each cable joint during early wiring and later maintenance wiring, which obviously brings additional troubles to wiring personnel

Third, due to the integrated structure of the shell and the panel of the traditional transmitter, and the panel is often equipped with fragile and vulnerable parts such as handles, operation buttons and even the socket of the launch assembly; Under the premise of the integrated structure with the panel, how to quickly replace the panel has become a difficult problem, which has brought great trouble to the actual maintenance personnel
