Impulse response of the UWB channel with perfectly and non perfectly conducting

In the paper there is presented the 2D time-domain model of two bare convex obstacles model, which includes an application of an amplitude and the first order transition zone diffraction process, called slope diffraction. The considered model is represented by its impulse response. Thanks to the usage of some approximations the formulation for this impulse response can be presented in a closed form. The applied method of deriving the 2 bare convex obstacles model can be extended for the case of more cascaded convex obstacles in the channel. The method uses uniform theory of diffraction (UTD) formulated in the frequency domain (FD). The accuracy of the derived model is examined in the process of calculation of an ultra wide band (UWB) pulse distortion.
