Abstract
Range gate delay is effected by serially connected coarse and fine programmable delay lines. The radar transmit trigger pulse is propagated through the programmable delay lines to provide a delayed trigger pulse. The delayed trigger pulse triggers a range gate generator for generating the range gate. The delay effected by the coarse and fine programmable delay lines is controlled from the system CPU. The range gate generator comprises a D-type flip-flop with the Q output thereof connected as the input to a further programmable delay line. The delayed trigger pulse sets the flip-flop and the output of the further programmable delay line resets the flip-flop. The range gate is provided by the Q output of the flip-flop. The width of the range gate is determined by the delay set into the further programmable delay line by the system CPU.
