Abstract
Digital beam array navigation signal simulator is a kind of important equipment to develop, test and verify multi-element anti-jamming satellite navigation terminal with cables. According to the working principle of anti-jamming satellite navigation terminal, the carrier phase consistency is a key indicator to signal simulator. Thus, measurement and correction of carrier phase consistency is an important part in the design of digital beam array signal simulator. In this paper, for this problem, an innovative technical solution is proposed for high-precision calibration based on carrier interferometer. This solution uses two array elements to measure delay mutually, based on the signal phase of one, directly detecting the phase of another. After analysis of theory and validation of experiment, the solution can achieve high measurement accuracy that is less than 0.1° of the relative phase among the array elements, and the price is small.
