Abstract

The invention relates to a multi-ring radio signal direction-finding algorithm. The algorithm comprising the following steps: step one, collecting a sample value; step two, carrying out direction finding by using a coarse capturing ring to obtain a first radio bearing direction and carrying out interpolation on the first radio bearing direction to obtain a second radio bearing direction; step three, carrying out direction finding on the second radio bearing direction by using a fined capturing ring to obtain a third radio bearing direction, and carrying out interpolation on the third radio bearing direction to obtain a fourth radio bearing direction; and step four, carrying out direction finding on the fourth radio bearing direction by using a refined capturing ring to obtain a fifth radiobearing direction being a current radio bearing direction. Therefore, a multi-ring radio signal direction-finding algorithm can be implemented.

Description

technical field [0001] The invention relates to the field of radio direction finding, in particular to a multi-loop radio signal direction finding algorithm. Background technique [0002] When using the correlation interferometer theory for direction finding, it is necessary to perform a correlation algorithm based on the currently measured phase difference and the sample to obtain the most relevant azimuth, which is the incoming wave azimuth. The azimuth step determines the accuracy of the incoming wave azimuth measured by the system. Take the index requirement of 1° as an example: the current phase difference and the phase difference of each degree of 360° in the sample are correlated to obtain the result. There are two ways to implement this operation: one, if a serial structure is used, it will take a lot of time, and the direction finding result will lose its effectiveness; the other, if a parallel structure is used, a lot of hardware resources will be spent.
