Embodiment 1

[0084] A multi-channel transceiver of anti-collision equipment, including a multi-channel receiver module, a multi-channel transmitter module, an integrated signal processing module, and an internal calibration source module arranged in the multi-channel receiver module; the internal calibration source module receives from The calibration command of the integrated signal processing module generates a calibration signal and enters the multi-channel receiver module; in the multi-channel receiver module, the amplitude and phase values ​​of a certain channel are used as a reference to correct the amplitude and phase differences between other channels and the reference channel Processing, the amplitude and phase consistency between the calibrated channels is satisfied, and the receiving channel calibration is completed; in the multi-channel transmitter module, through the internal communication interface between the multi-channel receiver module and the multi-channel transmitter modu...

Embodiment 2

[0086] On the basis of Embodiment 1, the multi-channel receiver module includes multiple receiving channels, and the signal received by the antenna enters the receiving channel. After limiting, the dielectric filter at the front end realizes the selection of the received signal, and completes the out-of-band Signal suppression, at the same time realize the mirror frequency, intermediate frequency suppression index, and the requirements of the out-of-band intermodulation index together with the LTCC low-pass filter behind; then enter the mixer for down-mixing after being amplified, filtered, and amplified by the LNA to generate The first intermediate frequency signal and the second intermediate frequency signal; the first intermediate frequency signal is the intermediate frequency signal corresponding to the C / S mode response signal generated by the TCAS inquiry target machine, corresponding to the first radio frequency receiving signal, and the up and down multiple radio frequen...

Embodiment 3

[0088] On the basis of Embodiment 1, in the multi-channel transmitter module, the transmitted local oscillator LO_TX signal and the baseband I / Q signal are filtered and mixed to generate the transmitted signal, which is sent to the power amplifier after passing through the filter and power control, and then amplified Then enter the switch network, and output to the transmitting antenna through the circulator; only when the channel transmits enable is valid, the amplifier of the channel will work, otherwise the link amplifier is off; Enable the control selection switch to attract the local oscillator signal LO_TX with the load.

Abstract

The invention discloses a multi-channel transceiver of anti-collision equipment and an amplitude-phase calibration method, and belongs to the technical field of air anti-collision systems. The multi-channel transceiver comprises a multi-channel receiver module, a multi-channel transmitter module, a comprehensive signal processing module and an internal calibration source module arranged in the multi-channel receiver module. According to the invention, auxiliary instruments such as external upper computer software and a power meter can be avoided, the amplitude and phase calibration of the signal can be automatically completed, and correct judgment of the diversity function of upper and lower antennas of the navigation management response and the TCAS azimuth measurement precision are guaranteed. No staff participates in the calibration process, the device automatically controls related hardware to complete amplitude and phase calibration of a transmitting and receiving channel according to an internal calibration module, and a calibration value is stored in a nonvolatile memory, so that the efficiency and the accuracy of product production debugging are improved.

Description

technical field [0001] The present invention relates to the technical field of aerial collision avoidance systems, and more specifically, relates to a multi-channel transceiver of anti-collision equipment and an amplitude and phase calibration method. Background technique [0002] Air collision avoidance system (TCAS: Traffic Collision Avoidance System), realizes the monitoring of other aircraft equipped with A / C / S mode transponders, and obtains the distance, azimuth and altitude of the target aircraft relative to the aircraft through calculation. Monitor the trajectory of other aircraft to determine whether it poses a potential collision hazard to the aircraft, determine whether there is a potential conflict threat in the air separation at the closest approach point, and output avoidance recommendations to the pilot. [0003] The traditional anti-collision system consists of one anti-collision processing host and two air traffic control transponders. The anti-collision proc...
