Problems solved by technology

[0002] At present, the communication function on the helicopter is mainly realized by the communication station. Due to the slow transmission rate of the communication station, it is impossible to transmit a large amount of information.
The helicopter platform cannot timely transmit the battlefield situation and formation coordination information to the command station, which makes it impossible for decision makers to obtain real-time comprehensive information on the battlefield detected by the helicopter sensor equipment, resulting in the helicopter's target strike capability and battlefield survivability Greatly reduced

Embodiment Construction

[0041] Now in conjunction with embodiment, accompanying drawing, the present invention will be further described:

[0042] The present invention includes the design of the overall timing relationship of the radar and the data link, and two aspects of the directional antenna beam alignment method, which mainly include the following steps:

[0043] (1) According to the radar antenna and RF front-end indicators and the requirements of data rate and communication distance, the link budget is determined to determine the signal and channel coding method;

[0044] (2) The helicopter platform communicates with the command station to "shake hands", and performs time alignment and establishes the current communication cycle according to the instructions of the command station;

[0045] (3) Establish the radar data link compound timing according to the current communication cycle information;

[0046] (4) Data link communication time slot, the helicopter platform performs beam alignment...

Abstract

The invention relates to a helicopter radar data link integrated radio frequency design method. A data link, a radar common antenna and a radio frequency front end can build a directional data transmission link between a helicopter platform and a ground control station, and the directional data transmission link is used for SAR image transmission, information interaction, path planning, and instruction guidance.

Description

technical field [0001] Helicopter radar data link integrated integrated radio frequency system is an integrated radar communication design. The data link and radar share the antenna and radio frequency front end, and a directional data transmission link can be established between the helicopter platform and the ground control station for SAR image transmission. , information exchange, route planning and command guidance. Background technique [0002] At present, the communication function on the helicopter is mainly realized by the communication station. Due to the slow transmission rate of the communication station, it is impossible to transmit a large amount of information. The helicopter platform cannot timely transmit the battlefield situation and formation coordination information to the command station, which makes it impossible for decision makers to obtain real-time comprehensive information on the battlefield detected by the helicopter sensor equipment, resulting in...
