Sentence examples for a steering vector from inspiring English sources

b j is calculated by using a steering vector and noise subspaces.

In [21], a steering vector estimation method is developed based on maximum output power criterion and subspace rotation.

Consequently, the optimized solution c opt may not be in the form of a steering vector either.

Remarks: (1) Note that the eigenvector (widehat {mathbf {gamma }}^{widehat {mathbf {Q}}_{theta }}_{text {min}}) may not be necessarily in the form of a steering vector.

Then, a steering vector for the whole array is given by a = a 1 e j ( 2 π ∕ λ ) R sin θ a 2 , (5).

where a is a steering vector with all ones, which is because the ultrasonic echo signals used for covariance matrix calculation are already delayed and aligned.

Therefore, target returns are described as the tensor of an unknown complex vector and a Doppler steering vector with an unknown Doppler shift.

When targets are without range walking across cells and the Doppler spread can be negligible during integration, target return vectors are modeled as the tensor of a complex HRRP and a Doppler steering vector [6]: s m, n = a ( m ) exp ( 2 πjn T r f d ), m = 0, 1, ⋯, M − 1, n = 0, 1, ⋯, N − 1, (4).

The original problem is optimized to maximize the output SINR and to force a similarity constraint with a quiescent steering vector exhibiting some desirable properties.

If the ({{tilde {mathbf {a}}}_{S}}) obtained by (28) is closer to actual value than ({{hat {mathbf {a}}}_{S}}), we preliminary think that the following iteration implementation will obtain a better steering vector and simultaneously obtain a better weight vector, step by step.

That is, A = [a θ1) a(θ2) … a(θ D )] with the steering vector a(θ d ) corresponding to the direction θ d given by: a θ d = e j k 0 x 1 sin θ d, …, e j k 0 x 2 M + N - 1 sin θ d T. (3).
