ATSEP -SURVEILLANCE TEST QUESTIONS
AND ANSWERS
Beam Width
What determines the range resolution of radar systems?
Azimuth Resolution
Measure of how well a radar can differentiate two targets with different
bearings but the same range.
Range resolution
Measure of how efficiently a radar can differentiate two targets with the same
bearing but differing range.
1030 MHz
frequency of the interrogator

frequency of the transponder
In Mode A, the distance between two pulses is 8us.
21 us
Distance between two pulses in Mode C.
, elevation, azimuth, range.
A 3D radar measures
scattering capability of the target
Radar cross section means:
matching filters.
What filter does the receiver have?
DPSK Uplink Modulation

Garble is a major issue in the design of traditional SSR systems, exacerbated by
growing traffic.
8-12 X-band range.
Received Response Intended for Other Interrogator
