| titleOfInvention | Multipath signal direction-of-arrival estimation method with large diffusion angle |
| abstract | The invention belongs to the technical field of signal processing, and relates to a multipath signal direction-of-arrival estimation method with a large diffusion angle. The specific scheme comprises the following steps: the method comprises the steps of modeling signals by adopting a distributed information source model, restraining impulse noise by adopting correlation entropy, defining self-adaptive kernel length, calculating a covariance matrix containing the correlation entropy, transforming a DSPE algorithm based on a high-precision noise subspace from a complex number domain to a real number domain, reducing calculation complexity through a unitary transformation pole, decomposing characteristic values of the covariance matrix and constructing a two-dimensional space spectrum, and searching and solving the direction of arrival and the diffusion angle of a target signal source by utilizing a two-dimensional spectrum peak. |
