In early February 1953, the radar training of the V? Pir Division was con.
ducted with the aid of a radar set, the type. of which could not be deter-
mined, which had been furnished by the Russians.
I
The effectiveness of the radar set is dependent on the number, type, alti-
tude and distance of the aircraft, as well as to the position of aircraft
and radar station. The following data were given:
Altitude of Aircraft Range of Radar
2,,000 'meters
4,000 r eters
6,000 meters
8,000 meters
65 kilometers
100 kilometers
120 kilometers
150 kilometers
3,, The area of the radar set has to be cleared from all obstacles which might
interfere with the relays (radiation) of the waves, at a radius of 5C0 to 600
meters.
4. The average error in measurer?ent at an azimuth angle of 2 degrees amounts
700 meters. Taking bearings to altitudes below 4,00C met-a!rs the error in
i2easurement is ? 300 meters, and to altitudes between 4,000 and 09000
meters - 500 meters.

6. Operation. During sumr!er months,four hours are required to erect
the radar set, and during the winter months, six hours are
required for the procedure. The set is ready for operation 3 to 5
r^inutcs after it has been turned on. The starting tire of the
generator is three minutes in surrrrer and 5 to 8 minutes in winter.
Fuel consumption of the generator: 335 ra ms gasoline and 17 granms
oil per hp per hour. After six hours of continuous operation, a
second generator has to be turned on.l
] I1 Comr.ent, it is believed that the data given refer to the
approximate figures of the Pumbo or SCR-602 radar sets'. The
average error in measurement is probably toy-high, while the fre-
quency range of the receiver is Yelieved to be too small.. The
trsining was performed in connection with early warning stations.
