Abstract EN
We propose a new algorithm to suppress the jammer signals and estimate the direction of arrival (DOA) of the signal of interest (SOI) for collocated MIMO radar by using the matrix pencil method (MPM) and the generalized likelihood ratio test (GLRT).
The conventional GLRT divides the visible region into small angle samples, suppresses the jammer signals at each angle sample, and then estimates the DOA of the SOI.
In the proposed algorithm, we extract the eigenvalues of received signals regardless of the SOI and jammer by using the MPM, which contain the information of the DOA of SOIs or jammers.
Then, in order to suppress the jammers, we apply the GLRT to the extracted DOAs instead of to the entire visible region.
By applying the MPM again to the received signals in which the jammer signals are suppressed, we can estimate the DOAs of the SOI.
Since the proposed algorithm does not depend on the number of angle samples, it shows fast and accurate results regardless of the angle resolution.
In order to verify the proposed algorithm, we compared the results with the results of the conventional GLRT and show the computing time.
