Description

Technical Field

[0001] This invention relates to the field of satellite communication technology, and in particular to an integrated communication measurement system and method for a phased array communication system. Background Technology

[0002] With the development of space communication technology, phased array communication systems have been applied to spacecraft. During operation, spacecraft need to control the beam direction of the phased array antenna in real time based on their own attitude, position and other information to achieve two-way communication with communication satellites.

[0003] To ensure the normal operation of the phased array communication system, communication tests need to be conducted on the ground. Due to the complexity of the phased array communication system, the current approach is to conduct distributed ground tests, testing each device of the system individually. This results in a wide variety of test devices with complex components, low testing efficiency, and difficulty in reflecting the overall system status. Furthermore, since the aircraft needs to achieve continuous communication with the communication satellite while in high-speed motion, it is difficult to simulate the actual high-dynamic flight state on the ground. Therefore, the ground testing and verification methods for the phased array communication system are inefficient and insufficient. Summary of the Invention

[0004] This invention provides an integrated communication measurement system and method for a phased array communication system, which solves the problems of complex, inefficient, and unreflective ground-based distributed testing methods for phased array communication systems of aircraft, as well as the difficulty in simulating actual high-dynamic flight conditions on the ground and the low efficiency and inadequacy of ground-based testing and verification methods for phased array communication systems.

[0005] To achieve the above objectives, the present invention provides an integrated communication measurement system for a phased array communication system, comprising a phased array communication system, integrated testing equipment, a power supply, a turntable, and a controller;

[0006] The phased array communication system includes a phased array antenna and a Ka-band relay system, which are installed on a turntable. The controller is connected to the turntable and is controlled by the PC board of the integrated test equipment. The phased array antenna can establish uplink and downlink radio frequency links with the satellite, and the Ka-band relay system can establish uplink and downlink radio frequency links and control and status information links with the phased array antenna.

[0007] The integrated test equipment consists of up / down frequency conversion boards, bus test boards, telemetry / remote control and command boards, integrated baseband boards, and PC boards. The up / down frequency conversion boards, bus test boards, telemetry / remote control and command boards, and integrated baseband boards are all connected to the PC board via a PCI bus. The up / down frequency conversion boards can establish uplink and downlink RF links with a phased array antenna. The bus test boards can establish bus data links with a Ka-band relay system. The telemetry / remote control and command boards can establish telemetry, remote control, and power-on / off command data links with a Ka-band relay system. The integrated baseband board can establish uplink and downlink RF links with the up / down frequency conversion boards.

[0008] The power supply provides power to the phased array communication system, integrated testing equipment, turntable, and controller.

[0009] To achieve the above objectives, the present invention also provides an integrated communication measurement method for a phased array communication system, applicable to the integrated simulation test system of the aforementioned phased array communication system, comprising:

[0010] (1) Joint testing of phased array communication system

[0011] The integrated test equipment establishes uplink and downlink RF links with the Ka-band phased array relay system through up / down frequency conversion boards, establishes bus data links with the Ka-band phased array relay system through bus test boards, and establishes telemetry, remote control, and power-on / off command data links with the Ka-band phased array relay system through telemetry / remote control and command boards.

[0012] The integrated test equipment uses a PC board to control the telemetry / remote control and command board to generate power-on and power-off commands and send them to the Ka-band phased array relay system, thereby realizing the power-on and power-off control of the phased array communication system.

[0013] The integrated test equipment uses a PC board to control a comprehensive baseband board to simulate and generate remote control information. After encoding and modulation, the information is sent to the up / down conversion board. Under the control of the PC board, the up / down conversion board generates an uplink RF signal, which is then sent to the Ka-band phased array relay system via a phased array antenna. The Ka-band phased array relay system receives the uplink RF signal, demodulates it, and sends the remote control data to the telemetry / remote control and command board of the integrated test equipment. The PC board compares the remote control data received by the telemetry / remote control and command board with the simulated remote control information to test the uplink performance compliance.

[0014] The PC board in the integrated test equipment simulates and generates aircraft telemetry data and sends it to the Ka-band phased array relay system through the telemetry / remote control and command board. After processing, the Ka-band phased array relay system generates downlink radio frequency signals and sends them to the up / down conversion board of the integrated test equipment. Under the control of the PC board, the up / down conversion board downconverts the signal into an intermediate frequency signal and sends it to the integrated baseband board. After demodulation by the integrated baseband board, the PC board compares the simulated aircraft telemetry data with the downlink performance indicators to test the compliance of the downlink.

[0015] (2) Phased array communication system satellite-to-ground wireless docking test

[0016] The integrated test equipment controls the Ka-band phased array relay system to establish uplink and downlink radio frequency links with the satellite and satellite ground control station. The integrated test equipment establishes uplink and downlink radio frequency links with the Ka-band phased array relay system through up / down frequency conversion boards, establishes bus data links with the Ka-band phased array relay system through bus test boards, establishes telemetry, remote control and power-on / off command data links with the Ka-band phased array relay system through telemetry / remote control and command boards, and establishes turntable control data links with the Ka-band phased array relay system through PC boards.

[0017] The integrated test equipment uses a PC board to control the telemetry / remote control and command board to generate power-on and power-off commands and send them to the Ka-band phased array relay system, thereby realizing the power-on and power-off control of the phased array communication system.

[0018] The PC board in the integrated test equipment outputs turntable control information based on the actual flight trajectory and attitude characteristics of the aircraft to control the turntable to simulate the position and attitude changes of the aircraft during flight. At the same time, the PC board sends the aircraft position and attitude data corresponding to the turntable control information to the Ka-band phased array relay system through the bus test board. The Ka-band phased array relay system controls the phased array antenna beam switching based on the received aircraft position and attitude data, tracks and keeps the beam pointing to the satellite, and simulates the high dynamic communication between the Ka-band phased array relay system and the satellite during the actual flight of the aircraft.

[0019] The satellite ground control station simulates and generates remote control information and modulates and transmits uplink radio frequency signals. The uplink radio frequency signals are relayed by the satellite to the Ka-band phased array relay system. The Ka-band phased array relay system receives and demodulates the remote control data through the phased array antenna and sends it to the telemetry / remote control and command board of the integrated test equipment. The PC board compares the remote control data received by the telemetry / remote control and command board with the remote control information simulated by the satellite ground control station to test the uplink performance compliance.

[0020] The PC board in the integrated test equipment simulates and generates aircraft telemetry data and sends it to the Ka-band phased array relay system via the telemetry / remote control and command board. After processing, the Ka-band phased array relay system generates downlink radio frequency signals, which are transmitted to the satellite by the phased array antenna. After being relayed by the satellite, the telemetry data is received and demodulated by the satellite ground control station and compared with the aircraft telemetry data simulated by the integrated test equipment to test the compliance of the downlink indicators.
