The invention discloses a beam forming method in a pulse noise environment, a storage device and a beam former. The method comprises the following steps: obtaining sample data collected in a preset antenna array of a base station, performing outlier detection on the sample data, and eliminating abnormal data; restoring missing data in the sample data by using the matrix filling technique, and solving a weighted vector by using the restored sample data; and performing weighted summation on the sample data according to the solved weighted vector to obtain the output of beam forming. By adoptionof the beam forming method provided by the invention, the influence of pulse noise can be effectively suppressed, high precision measurement of data signals under the interference of the pulse noise can be realized, the robustness of the beam forming is improved, and it is conducive to realizing a higher output signal to interference plus noise power ratio.
Description
technical field [0001] The invention relates to the technical field of adaptive beamforming, in particular to a beamforming method, a storage medium and a beamformer in an impulse noise environment. Background technique [0002] Adaptive beamforming technology is widely used in many fields, such as phased array radar systems, active sonar, seismology, medical imaging, etc. The theory of adaptive beamforming technology still faces many practical problems from knowledge to engineering application. Among them, the premise of most of the theoretical work is to assume that the environmental noise conforms to the Gaussian distribution, but in practical applications, due to various factors, the environmental noise is often impulsive noise. [0003] In the prior art, in order to improve the robustness of beamforming in an impulsive noise environment, a beamformer based on Fractional Low-Order Statistics (FLOS) theory can be used to solve the weighting vector. Although this method ...
