ABSTRACT:
The paraxial, c.w. focal zone resolution of a focussed scanning imaging system is improved by choosing the ratio of the size of the apertures which are used to transmit and receive energy from the scene such that the first and second sidelobes of the system point spread function have equal amplitudes.
