The phrase "a steering vector for" is correct and usable in written English.
It can be used in contexts related to guidance, direction, or control, often in technical or scientific discussions.
Example: "The algorithm utilizes a steering vector for optimizing the path of the robotic arm."
Alternatives: "a guiding vector for" or "a direction vector for".
where α is a constant, ({{tilde {mathbf {a}}}_{S}}) is an equivalent steering vector for MPDR beamformer, and we guess that ({{tilde {mathbf {a}}}_{S}}) is more accurate than ({{hat {mathbf {a}}}_{S}}) if w WCB (obtained by (23)) is better than w MPDR (obtained by (5) with ({{hat {mathbf {a}}}_{S}})).
For a weight vector obtained by WCB or other beamformers, we can define an "equivalent steering vector" for MPDR beamformer.
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.
To make use of the information about a steering vector contained in past STI windows, a recursive algorithm is developed to estimate the posterior PDF of the steering vector.
Here we let AD 1 2 = H = [ h 1 h 2 ⋯ h N ] with h i = d i a(θ i ) be the scaled steering vector for i = 1, 2, ⋯, N. Since C(k) is a diagonal matrix formed from the periodic modulation sequences c 1 k), c 2 k), ⋯, c N (k) with period P by assumption (iii), we know that C k 2 is also periodic with period P, i.e., C k 2 = C k + P 2, which implies that R k+P = R k, for example, R 1 + P = R 1.
In this paper, a recursive Bayesian approach is proposed to mitigate uncertainty in the steering vector for narrowband beamforming.
Thus, the clutter steering vector for each pixel is reformatted to be a vector of ones, followed by the transformed covariance matrix which takes the form.
denotes the receiving steering vector for incident angle ϑ.
Steering vector for the proposed array is represented with aPA(θ m ) that is a (N + 2) × 1 vector and it can be written as: (7).
