Each bar takes a specific amount of time for the radar to search,
so it is not always advisable to select the maximum bar sweep.
For example, if you know the bandits altitude as you approached,
you do not need a 4-bar scan. You can put more radar energy out
there and increase your probability of detection if you scan with
fewer bars. Along with selecting the bar scan, the pilot can also
crank the entire search volume up or down. If the bandits are
running in on the deck, you can select a 1-Bar scan and crank
down to search the deck for the targets. In a 1-bar scan, you
are searching the area of interest faster because you are not
wasting radar sweeps searching empty air space.
go into combat with your wingman, you should have a radar search
plan. Normally, you don't want to have all the radars in the flight
searching the same piece of sky. In many cases, GCI will call
out targets and get you pointed at the enemy. if you know the
target's altitude, then you can select a smaller elevation scan
pattern (fewer bars). Most of the time, however, you will want
to search the greatest volume of airspace, selecting the maximum
number of bars.
Once you have detected the bandits, you must sort them. Sorting
is the process of determining the following information about
- How many are
- What formation
are they in?
- What are they
As soon as each fighter in the flight completes his sort, he must
pass the information to the rest of the flight. This communication
serves several purposes. First, you are passing along your radar
situational awareness (SA) to the other flight members, which
will build their SA. Second, you are comparing radar pictures
of the air battle, which helps you confirm that you are seeing
what you think you are seeing. Here is an example of the radio
calls during a sort.
has a two ship, line-abreast, high-aspect. South target is at
angels 22. North target is at angels 20."
has a single high-aspect target at angels 22."
From this call,
you can tell that number 2 has not detected one of the bandits.
He knows that there is another guy out there, and he should look
for him. The call by lead that the targets are at high aspect
answers the "what they are doing?" question. A high
aspect means that the enemy has his nose on you.
