Abstract :
The paper describes the application of a double transmission technique to linear arrays in order to obtain a directional response with a small beamwidth. An ideal system is analysed and experimental results obtained with a model of such a system are given. The theoretical and experimental results show that a reduction of the array beamwidth by a factor of two or four may be achieved by the use of additive or multiplicative processing respectively of the received signals. A practical time spaced transmission scheme is proposed and its application to within-pulse scanning radar systems is considered.
