| titleOfInvention | Method for estimating maximum likelihood angle resolution of sensor array system |
| abstract | The invention provides a method for estimating maximum likelihood angle resolution of a sensor array system, which comprises the following steps: establishing a uniform linear array of multiple sensor array elements, obtaining a likelihood function of an observed value by utilizing a receiving signal of an antenna, obtaining an actually estimated angle value by performing two-dimensional traversal and peak value search on the likelihood function, judging the resolving power of an array sensor system to a similar information source according to posterior probability distribution of angles counted under multiple fast photographing, and finally obtaining a theoretical resolution result through amplitude-phase information calculation. The invention can judge whether the information source can be distinguished or not through the number of the peaks appearing in the posterior probability, and the resolution precision of the invention is superior to that of the resolution obtained in the prior art. |
