7.8 Finding the location of a signal scource (Indoor)
Narda IDA - 3106
155
An indoor localization takes place in two steps:
1. Referencing:
Four points are defined as references in the room, and the
dimensions and azimuth are entered.
2. Localization:
Start localization, take bearings on the signal source from
the four reference points, save the results, and determine the position.
NOTE:
Remember that considerable reflections can occur, particularly in small
rooms. A minimum distance from the walls is also often recommended in
order to reduce field distortions. Indoor DF may not work as intended if the
rooms are small, with short distances between walls and objects. In such
cases, it is better to switch to Tone Search mode for locating the signal
source (see
Using the audio function
on page 132).
Referencing the room

1.
Specify the floor area of the room to be measured using four corners A
through D. The room sides must be at right angles to each other. (The
reference points normally correspond to the room corners.)
