Embodiment Construction
[0035] The fast subspace estimation method proposed by the present invention is described as follows with reference to the drawings and embodiments.
[0036] S101: Obtain an observation data model of an antenna array element;
[0037] A uniform antenna array (ULA) with M units receives P narrowband far-field signals. At the kth snapshot moment, the M×1-dimensional complex observation data can be expressed as:
[0038] x(k)=[x 1 (k),x 2 (k),...,x M (k)] T , k=1, 2, ..., N
[0039] =A(θ)s(k)+n(k) (1)
[0040] =[a(θ 1 ), a(θ 2 ),…, a(θ P )][s 1 (k), s 2 (k),...,s P (k)] T
[0041] +[n 1 (k), n 2 (k),...,n M (k)] T
[0042] where x M (k) represents the signal data of the Mth antenna element; s(k), A(θ) and n(k) represent the signal vector, steering matrix and noise vector respectively; N is the sampling support length, a(θ i ) means that the direction of arrival is θ i The signal-steering vector of and has the following form:
