An improved variant of the algorithm realizing a method of proportional guidance for the control of hypersonic unmanned aerial vehicles (UAVs) in a limited sector of angular tracking associated with the aerodynamic target line is considered. The meth

Two–dimensional (2D) linear frequency diverse array (FDA) concept is extended to scan a 2D wide angular sector. This is achieved by highly unequal frequency increments in orthogonal 2D directions of the array. The radar operates as a pulsed FDA in

Let A and $$\tilde{A}$$ be linear unbounded in general operators on a Hilbert space. We consider the following problem: let the spectrum of A lie in some angular sector. In what sector the spectrum of $$\tilde{A}$$ lies, if A and $$\tilde{A}$$ are su

This work is a natural continuation of our recent study devoted to the scattering of a plane incident wave by a semi-infinite impedance sector. We develop an approach that enables us to compute different components in the far-field asymptotics. The m

Let A and A be bounded operators in a Hilbert space. We consider the following problem: let the spectrum of A lie in some angular sector. In what sector the spectrum of A lies if A and A are “close”? Applications of the obtained results to integr
