[0001] The present 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 Art

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

[0003] To ensure that the phased array communication system can be used normally, it is necessary to perform communication tests on it on the ground. Since the phased array communication system is relatively complex, the current method of ground distributed testing is mostly used to test each device of the system separately. The test equipment is of many types and complex composition, the test efficiency is low, and it is difficult to reflect the overall status of the system. At the same time, since the aircraft needs to achieve continuous communication with the communication satellite during high-speed movement, it is difficult to simulate the actual high-dynamic flight state on the ground. The ground test verification method of the phased array communication system is inefficient and insufficient. Summary of the invention

[0004] The present invention provides an integrated communication measurement system and method for a phased array communication system, which solves the problems that the ground decentralized testing method for an aircraft phased array communication system is complex, the testing efficiency is low, it is difficult to reflect the overall state of the system, it is difficult to simulate the actual high-dynamic flight state on the ground, and the ground testing verification method for the phased array communication system is low in efficiency and insufficient.

[0005] To achieve the above objectives, the present invention provides an integrated communication measurement system for a phased array communication system, including a phased array communication system, an integrated test device, 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, and is installed on a turntable. The controller is connected to the turntable and is controlled by a PC board of an integrated test device. The phased array antenna can establish uplink and downlink radio frequency links with a 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 is composed of an up / down frequency conversion board, a bus test board, a telemetry / remote control and command board, an integrated baseband board, and a PC board. The up / down frequency conversion board, the bus test board, the telemetry / remote control and command board, and the integrated baseband board are all connected to the PC board via a PCI bus.

The telemetry / remote control and command board can establish a telemetry, remote control, and power on / off command data link with a Ka-band relay system. The integrated baseband board can establish an uplink and downlink radio frequency link with the up / down frequency conversion board.

[0008] The power supply is used to supply power to the phased array communication system, the integrated test equipment, the turntable and the controller.

[0013] The integrated test equipment controls the integrated baseband board through the PC board to simulate and generate remote control information, which is then sent to the up / down conversion board after encoding and modulation. The up / down conversion board generates an uplink RF signal under the control of the PC board through the phased array antenna and sends it to the Ka-band phased array relay system. The Ka-band phased array relay system receives the uplink RF signal and demodulates it before sending 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 indicator compliance of the uplink.

[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. The Ka-band phased array relay system generates a downlink RF signal after processing and sends it to the up / down conversion board of the integrated test equipment. Under the control of the PC board, the up / down conversion board down-converts 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 it with the simulated aircraft telemetry data to test the compliance of the downlink indicators.

[0018] The PC board in the integrated test equipment outputs turntable control information to control the turntable to simulate the position and attitude changes of the aircraft during flight according to the actual flight trajectory and attitude characteristics of the aircraft. 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 switching of the phased array antenna beam according to 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.
