Embodiment Construction
[0035] The present invention will be further described in detail below in conjunction with the accompanying drawings and examples, in order to understand the content of the patent application of the present invention more clearly, but the embodiments of the present invention are not limited thereto, and the patent of the present invention cannot be limited by this scope of protection.
[0036] Such as figure 1 As shown, the present invention is a GNSS cascaded adaptive multi-beam forming method, the purpose of which is to separate the anti-interference processing from the beam weighting, so that the anti-interference processing at the antenna end does not need the assistance of prior information such as satellite direction and antenna attitude, and the receiver end It is easy to achieve three-dimensional integrated search and tracking of space, time and frequency; at the same time, the array signal whitening process is completed by using the inversion of the autocorrelation sq...
