PSR ATSEP UPDATED ACTUAL Exam
Questions and CORRECT Answers
ASR system may employ a ___ to suppress not just ground clutters but also weather and other
mobile clutters. - CORRECT ANSWER - Multi Doppler Filter
What is the measure of how well a radar can distinguish two different targets of different bearing
but of the same range? - CORRECT ANSWER - Azimuth resolution
___ is an erroneous radar target caused by noise or other interfering signals exceeding the radar's
detection threshold. - CORRECT ANSWER - False alarm
What characteristic of the transmitted radar pulse determines the range resolution of a radar
system? - CORRECT ANSWER - Pulse width
What is the name of an adaptive algorithm in radar systems that varies the detection threshold as
a function of the sensed environment to maintain the desired number of false alarms? -
CORRECT ANSWER - Constant false alarm rate
Azimuth resolution of a radar system is determined what antenna characteristic? - CORRECT
ANSWER - Beam width
This method of determining the azimuth requires the radar to get the average between the leading
and the trailing azimuth of the target. - CORRECT ANSWER - Sliding window
This radar video signal consists of both MTI and clutters. - CORRECT ANSWER -
Normal Video
One principle used in radar systems is that EM waves travel at constant speed, this allows for
determining the ___ of the target. - CORRECT ANSWER - Distance
