基于超聲陣列傳感器與遺傳MUSIC的局放源波達(dá)方向估計(jì)
[Abstract]:DOA estimation based on ultrasonic array sensor is the basis of PD location. The accuracy and search success rate of the traditional MUSIC direction finding algorithm are low. A new method for DOA estimation of PD source based on ultrasonic array sensor and genetic MUSIC algorithm is proposed. Genetic MUSIC algorithm uses spatial spectral estimation formula to construct fitness function. Based on the idea of genetic iterative search, the spectral peak of azimuth is searched to obtain the global optimal solution. Through the establishment of signal model and array model, a large number of simulation experiments were carried out, and the results of direction finding of classical MUSIC and genetic MUSIC were compared based on the three indexes of searching accuracy, search success rate and search time. The results show that based on genetic MUSIC algorithm, the search success rate is improved, and the absolute accuracy is 0.3 擄less than that of the traditional MUSIC algorithm, and the DOA of PD source can be obtained with higher precision.
