The time delay effect on the pulse radiation of a tapered slot antenna array

The former of impulses is described on the basis of generators with steerable time delay in This work. The pulse radiation of TSA array was simulated numerically. In experiment the former consists of two generators of video pulses, of the power supply and the control unit. The generators nominal amplitude is about 300 V. The electronic regulator in the control unit provides delaying.

1. The Forming of Powerful Short Impulses

For the reception of a signal of the uprated power in the direction of supervision, it is suggested to use the radiation from several similar-type generators exciting two dimensional TSA array, which has directivity for definite parameters. We consider the spatial adding up of signals. The signal from the nth generator comes to an observation point in time later than from the 1st one, due to a different path length ( is the speed of a pulse propagation in the medium).
