Embodiment Construction
[0059] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0060] The present invention first establishes a multi-aircraft cooperative search and rescue direction finding model for the specific array structure of general aircraft, and proposes two non-equidistant direction finding schemes for the non-equidistant antenna array structure, and then analyzes the channel amplitude and phase error characteristics in the direction finding process The analysis is carried out, and the single auxiliary source correction algorithm is used to correct the error, so as to improve the direction finding accuracy in the search and rescue process. like figure 1 As shown, the specific steps are as follows:
[0061] 1. Optimizing the design of the structure of the non-equidistant array can reduce the number of continuous elements of the antenna array and increase the aperture of the array, thereby improving the direction finding ...
