Abstract

PURPOSE: To obtain required extended pulse width with excellent S/N, by providing a plurality of amplification systems having feedback loop different in delay time and changing over them in the order of the shortest delay time to longer on the way.
CONSTITUTION: The output of the high frequency amplifier 1 is fed back to the input side of the amplifier 1 via the delay lines 2 and 3. In this case, the delay time in the delay elements 2 and 3 is made different each other, and the location for a plurality of systems is made by using this amplifier 1 in common or independently. At the same time, the amplification systems are changed over 4 from the shorter delay time in the delay lines 2 and 3 to longer one. Thus, required extended pulse width can be obtained with excellent S/N without increase in the number of circulation circuits for reception signal.
