Range finder impulse interference suppression method combining direction of arrival (DOA) estimation and main beam forming

摘要: The invention provides a range finder impulse interference suppression method combining direction of arrival (DOA) estimation and main beam forming. comprises the steps that received radio-frequency signals from an array antenna are converted into analog baseband signals; digital number coming-direction information analyzed through estimator; forming weights coming directions all paths obtained linear constraint minimum variance method, is carried out; orthogonal frequency division multiplexing perpendicular incidence path according to signals, after forming, paths; Doppler offset values estimated, compensation cyclic prefixes further removed, conversion out so domain can be obtained, sent balancer being processed quadruple sampling, output by pass demodulator, deinterleaver decoder in sequence estimated value bit obtained. According DOA directly utilized for weighting array-received suppressed.
