Method for determining azimuth angle of target object, computer equipment and storage medium

Abstract

The invention relates to a method for determining azimuth angles of target objects, computer equipment, a storage medium, an integrated circuit, a radio device, a sensor and equipment, and belongs tothe technical field of target detection. The method for determining the azimuth angles of the target objects comprises the steps of obtaining a preset to-be-searched angle set; obtaining the number Nof target objects; performing N-dimensional search on the to-be-searched angle set based on maximum likelihood estimation; and based on the result of the N-dimensional search, obtaining the azimuth angle of each target object. The preset to-be-searched angle in the to-be-searched angle set is an equal function difference value, so that the calculation amount of calculating the function differencevalue of the adjacent preset to-be-searched angles online can be reduced in each iterative calculation process.

Description

[0001] This application claims the priority of the Chinese patent application submitted to the China Patent Office on February 28, 2020, with the application number 202010131565.9, and the title of the invention is "method, device, equipment and storage medium for determining the speed of an object", the entire content of which is passed References are incorporated in this application. technical field [0002] The present application relates to the technical field of target detection, in particular to a method for determining the azimuth angle of a target, computer equipment, storage media, integrated circuits, radio devices, sensors and equipment. Background technique [0003] When a sensor detects a target, it generally uses a Maximum Likelihood Estimation (MLE) method to determine the azimuth of the target. In this process, it is necessary to conduct an online search for the estimated results based on the number of targets. For example, if the number of detected targets ...

Problems solved by technology

For example, if the number of detected targets is n (n is a positive integer), an n-dimensional search needs to be performed on the estimated results, that is, iterative calculations need to be performed on different combinations of the n angles to be searched, because iterative calculations involve costs The calculation of the function will make the calculation amount of each iteration calculation very large

[0004] At the same time, in practical applications, since the sensor usually detects multiple targets at the same time, it is necessary to perform a multi-dimensional search on the estimated result based on the number of targets, which will increase the amount of calculation exponentially, thereby greatly reducing the sensor target. The efficiency of detection will also adversely affect the accuracy of target detection
