An IF amplifier and detector were designed for a noncoherent
MTI radar. The amplifier was designed to satisfy
the following two requirements:
A, The amplifier must not overload; saturation due to large
signals is not permitted.
B. When strong clutter is present, the amplifier must amplify
the peak of the signal, since the effects due to small
moving targets are carried in the peak of the resultant
signal
.
The performance of the AN/UPS-1 air search radar,
operated as a noncoherent MTI system with the modified IF
amplifier, was checked. This modification provides increased
sensitivity for the noncoherent MTI radar over a radar employing
a logarithmic IF amplifier. The advantage of noncoherent
MTI is its simplicity. It is therefore attractive for those
applications where space and weight are limited. It is also
attractive for airborne applications since no compensation
is required for radar motion.
