FUNCTIONAL DESCRIPTION
Frequency: 175 to 225 mc
Peak Power Output: 100 kw
Radar Equipments SA, SA-1, SA-2,and SA-3 are
Pulse Repetition Rate: 60 pps
lightweight, short range air-search radars that may also
Pulse Width: 5 sec
be used for surface search. They are used in both ship
IF. Frequency: 15 mc
and shore installations.
Bandwidth: SA - 1 mc if.; SA-2 - 0.7 mc if.
The SA and SA-1 are similar. The SA-1 employs
Noise Figure: 7 db
equivalent but slightly modified units. The SA-1 and SA-
