Answer 17

100 yd - 2 nm

Question 18

peri integration time in relation to sea state

Answer 18

the higher the sea state, the higher the integration time (PINT)

SIG or ESIG for general features

Answer 20

ESIG

Question 21

when do we get the A in the lower right corner of a symbol on ARPDD

Answer 21

once the signature has been viewed

Question 22

similarity in small target indicator for Peri and ARPDD small contact

Answer 22

both have S in upper right

Question 23

way to improve ISAR image in low sea states or low target speed

Answer 23

increase integration

Question 24

iff interrogator mode limitations within 100 nm of US, HAWAII or ALASKA

Answer 24

interrogate only IAW current national/local frequency assignments
1000’ AGL and below
only in slow scan modes
no more than 5 interrogators in one area
mode 3 3/c sweeps limited to 10 at a time
no Mil Mode

Question 25

IFF interrgoator limits more than 100 nm from us

Answer 25

only in slow modes

Question 26

iff interrogations above 7000’ DA

Answer 26

no with an inhbt intg or rdr/intg fail

Question 27

max number of radar/iff tracks

Answer 27

320

Question 28

tracks in the 153

Answer 28

actually tracks 2500 but only shows 320, 256 radar 64 iff

Question 29

what percentage should you keep radar tracks below

Answer 29

90%

Question 30

max number of windows and sectors

Answer 30

4 each

Question 31

do windows and sectors inhibit prob pd

Answer 31

no

Question 32

windows override sectors or sectors override windows

Answer 32

windows override sectors

Question 33

tracker sectors vs radiate sectors

Answer 33

tracker is only to prevent tracks from being made

radiate says do or do not radiate here (no prob pd)

Question 34

will we get prob pd in a land mass repair inhibit box

Answer 34

no

Question 35

does LSF declutter tracks above or below selected speed

Answer 35

below

Question 36

should we adjust gain

Answer 36

probably not
