Universal Approximator Property of the Space of Hyperbolic Tangent Functions

In this paper, first the space of hyperbolic tangent functions is introduced and then the universal approximator property of this space is proved. In fact, by using this space, any nonlinear continuous function can be uniformly approximated with any degree of accuracy. Also, as an application, this space of functions is utilized to design feedback control for a nonlinear dynamical system.

Tangent Measure Distributions of Hyperbolic Cantor

Tangent measure distributions were introduced by Bandt 2] and Graf 8] as a means to describe the local geometry of self-similar sets generated by iteration of contractive similitudes. In this paper we study the tangent measure distributions of hyperbolic Cantor sets generated by certain contractive mappings, which are not necessarily similitudes. We show that the tangent measure distributions o...

Joint Range and Angle Estimation Based on Sub- Array Scheme with Frequency Diverse Array Radar

Frequency Diverse Array (FDA) has its unique advantage in realizing Low Probability of Intercept (LPI) technology for its beam pattern is related to the range, time and angle. In this paper, a sub-array scheme of range-angle joint estimation of a target for Frequency Diverse Array (FDA) radar is proposed. To solve the problem of distance and angle response coupling of basic ULA FDA radar, the e...
