Title: Method and apparatus for estimating the number of signals, by considering SML cost function and hypothesis test
Inventor: SHIN DONG SEUNG
IPC: G01S3/04
Filed: 2018-09-20
Abstract: The present invention relates to a method for estimating the number of signals in consideration of an SML cost function and hypothesis verification preceding the arrival angle (DoA) estimation in a radar system for a vehicle, and to an apparatus thereof. According to the method of the present invention, following processes are executed. First, an initial DOA estimate is determined by using an SML cost function in a covariance matrix of a received signal. The initial number of signals is set to one. By using the determined initial DOA estimate, the number of signals is estimated by applying a GLRT method to the SML cost function. When the estimated value is greater than a certain threshold, one signal is added to the number of signals, and then the DOA estimation is continuously performed using an alternating projection technique. When the estimated value is not greater than a threshold value, the estimation of the number of signals is terminated.
