Problems solved by technology

[0002] The multi-channel amplitude-phase test system is based on DSSS and is applied to the amplitude-phase consistency test of the digital beamforming antenna array. In the existing antenna beamforming amplitude-phase test equipment, it is difficult to measure the absolute delay for a single-channel system. For multi-channel systems, it is limited to measuring the relative delay between channels

Abstract

The invention provides an antenna beam synthesizing phase absolute delay calibration device and method. The device comprises an attenuator module, a radio-frequency multi-channel switch module, a radio-frequency down-conversion module, an analog to digital conversion module, an intermediate frequency down-conversion module, a code capturing module, a code tracking module and a code phase carrier phase solver module, wherein the attenuator module, the radio-frequency multi-channel switch module, the radio-frequency down-conversion module, the analog to digital conversion module, the intermediate frequency down-conversion module, the code capturing module, the code tracking module and the code phase carrier phase solver module are sequentially connected. According to the invention, multi-channel absolute delay measuring is realized, and at the same time resources consumed by multi-channel ranging are reduced.

Description

technical field [0001] The invention relates to the field of signal processing, in particular to an absolute time delay calibration device and method for antenna beam synthesis phase. Background technique [0002] The multi-channel amplitude-phase test system is based on DSSS and is applied to the amplitude-phase consistency test of the digital beamforming antenna array. In the existing antenna beamforming amplitude-phase test equipment, it is difficult to measure the absolute delay for a single-channel system. For multi-channel systems, it is limited to measuring the relative time delay between channels. However, the measurement of the absolute time delay of the system is directly related to the system parameter index and the phase difference of the multi-channel signal arriving at the test interface. At the same time, due to the unpredictability of the carrier phase of the sending end of the system, the phase of the starting end can also be calculated by means of the absol...
