The invention discloses a method for estimating the performance of a sonar beamformer in an arbitrary array, comprising the following steps: S1, constructing an array space coordinate matrix, S2, transforming the array attitude, S3, establishing an array signal model, S4, forming a beam, S5 , Beam performance estimation. The present invention can directly select the preset common array form when designing the acoustic base array, and can also quickly obtain other irregular formations by loading the coordinate data of the array elements, and can change the spatial position of the acoustic base array by setting the attitude parameters. . The present invention can also select different beam formers after setting the signal parameters and beam parameters on the basis of the formation design is completed, draw horizontal direction, vertical direction and three-dimensional three-dimensional beam diagram, through the main lobe direction, main lobe height, The main lobe width, side lobe height, grating lobe height, etc. are used to estimate the performance of the beamformer. Comparing the beam performance under different parameters and algorithms can facilitate the designer to optimize the sonar parameters and beamforming algorithms.
Description
technical field [0001] The invention belongs to the technical field of sonar array signal processing, and in particular relates to a method for estimating the performance of a sonar beamformer in an arbitrary formation. Background technique [0002] Sonar is an electronic device that uses sound waves to detect, locate and communicate underwater targets. There are many types of sonar, and there are many classification methods. It can be broadly divided into two categories: military and civilian; according to the working principle or working method, it can be divided into active sonar and passive sonar; according to the device system, it can be divided into ship sonar, submarine sonar, shore sonar Sonar, aerial sonar, sonobuoy, submarine sonar, etc.; classified according to the nature of work, it can be divided into communication sonar, detection sonar, underwater guidance sonar, underwater acoustic countermeasure system, etc. But all sonars have something in common, with a ...
