Embodiment Construction
[0036] The present invention will be further described below in conjunction with the accompanying drawings.
[0037] Step (10), performing class normalization preprocessing on the signal data vector received by the uniform line array, to obtain data z(t) that has undergone class normalization preprocessing;
[0038] Step (20), divide the uniform linear array into several sub-arrays, use the PAST algorithm to process the data of the sub-arrays, and obtain the signal subspace data U of the incident signal when the number of snapshots is t S (t);
[0039] Step (30), using the MUSIC algorithm to process the data in the signal subspace, and obtaining the direction of arrival of the target signal through spectral peak search;
[0040] Step (40), input the signal data vector of the next snapshot, go to step (10).
[0041] Wherein, step (10) further includes:
[0042] Step (110), obtaining the data vector received by the array element, taking the absolute value of the elements in t...
