A method of direction of arrival (DOA) and direction of departure (DOD) angle estimation based on polynomial rooting for bistatic multiple-input multiple-output (MIMO) radar with uniform circular array (UCA) configuration is proposed in this paper. The steering vector of the UCA is firstly ...
Here, the concepts of the Wavefield modeling for scalar-fields are given. Two expressions for decomposing the steering vector (manifold) of array elements with sparse UCAs are presented. These form the theoretical basis of our algorithm. In [10], it is shown that the array steering vector is ...
This study makes use of the UCA heading information and the properties of the UCA steering vector to address this problem. A two-step spatial rotation procedure is devised to rotate the source DOAs from array coordinates to geodetic coordinates in real time, and consequently, the UCA remains ...

where a(θ,t) is the M×1 array steering vector, v(n) the M×1 vector of i.i.d. complex Gaussian zero-mean noise samples, and N the number of samples. The Pth order PPS x(t) is defined as (105)x(t)=Aejϕ(t)=Aej∑k=0Paktk, where A is the amplitude, ϕ(t) the ...
A Uniform Linear Array (ULA) is a collection of sensor elements equally spaced along a straight line. The most common type of sensor is a dipole antenna that can transmit and receive Electromagnetic Waves over the air. Other types of sensors include acou

The constitutive behavior of the rectangular slab and the circular cylinder will be discussed next. More specifically, we first generalize the result of Chau and Rudnicki [4] to solids described by (2.1), which is to be given in the next section. The constitutive behavior of the circular ...
Previously several types of configurations of the transducers such as linear [11], rectangular [10], spiral [12], or circular [13] arrangements are introduced based on the applications. By changing the time delay between excitation of every transducer, the steering direction can be changed. Despi...
