search radar
What radar continuously scans a volume of space and provides the initail detection of all targets within that space.
|
decrease- closer = increase
as a target moves away there is an apparent what in frequency and vice versa
|
syncronizer
What ensures all circuits in the system operate in a definite timed relationship and times the interval between tx and rx pulses
|
aircraft, f18, mim
What is this pub used for?
navair-01-fa18ea-2 |
keep reflects from being driven into its mechanical stops
What is the purpose of tilt limit switches
|
|
range, bearing, altitude
What does 3d radar provide
|
Continuos Wave Method cw
What is the best means for detecting fast moving objects when range resolution in not required
|
transmitter
What generates powerful pulses of electromag energy @precise intervals and prduced very high voltage, currents, and microwave rad levels that are extremely dangerous
|
aircraft identifying radar test set
What does ts/apx-72a designate?
|
FTC
What emphaseized the leading edge and deemf the remained of vid and is effective in reducing clutter caused by rain, snow, and sea returns
|
|
tracking radar
What is used primarily as a fire control radar
|
162,000 nm/sec
What is the speed of light rf energy travels at
|
dummy load
What is a devise used at the end of a tx or wg to convert tx energy into heat.
|
50 ns mstr trig pulses at prf's 600,700,800,1000hz
What does the master trig gen card produce?
|
reflex klystron
What is another name for a special vaccum tube oscillator
|
|
must take into account thr movement of the ship
how does cca differ from gca
|
PW
min range+pw/ 12.36
micros what determines minimum range and what is the formula
|
duplexer
What permits the use of one antenna to both tx and rx
|
+, -, ref. via sync trig
When does the sweep gen card produce its three outputs and what are they?
|
cancels most local oscillator noise
What is the advantage of a balanced xtal mixer mounted in a sect of wg w/in the rx
|
|
space and weight
airborne radar is designed to meet what two limitations
|
12.36 micro s
What is one radar range mile equivelant to
|
frequency stability & be extremely sesnitive. be completly iso from tx pulses
the receiver must have what two things? and be completely isolated from what?
|
antenna
the range marks, hdg mrks gen cr produces a marker pulse when a heading marker trig is received from what component?
|
+/- 200 Mhz to prevent jamming
What is the frequency of the magnetron continuously varied to and why?
