Title:
CONJUGATE GRADIENT-BASED ARRAY ANTI-INTERFERENCE METHOD
Document Type and Number:
WIPO Patent Application WO/2021/174683
Kind Code:
A1
Abstract:
A conjugate gradient-based array anti-interference method. The method comprises the following steps: step 1, constructing a signal model-based optimization problem model for adaptive array anti-interference for satellite navigation positioning, radar detection, and wireless communication application scenarios; step 2, on the basis of conjugate gradient theory, solving for a weight of each antenna or sensor in an adaptive array by using a conjugate iterative algorithm having low complexity; and step 3, solving for the weights in real time by using a field programmable device. By using conjugate gradient-based iterative weight calculation, the complexity of the traditional algorithm can be effectively reduced, fast adaptive anti-interference calculation can be achieved, and the real-time anti-interference needs of a moving device can be met.
