Embodiment Construction
[0036] The space-time blind adaptive GPS interference suppression method based on the de-respreading technology of the present invention will be described in detail below in conjunction with the embodiments and accompanying drawings. Although this embodiment is discussed with a uniform linear array as an example, the invention is applicable to Arbitrary array.
[0037] like Image 6 As shown, the space-time blind adaptive GPS interference suppression method based on the de-respreading technology of the present invention is to combine the minimum power method and the de-respreading technology, and adopt the space-time adaptive antenna array to realize, including the following steps:
[0038] The first step is to use the weight vector calculated by the space-time minimum power algorithm as the initial weight vector of the space-time adaptive GPS anti-jamming array; including: firstly establish the space-time adaptive array receiving data model, and then calculate the initial wei...
