5  RADAR TRANSMISSION CONFIGURATION 
5.1  CONFIGURING THE RADAR TARGET AZIMUTH UPDATE 
 
The target azimuth update is the azimuth angle at which each radar scan starts. Around this region, the 
tracking of targets and intruders may be sub-optimal. It is recommended to set this parameter to an azimuth 
outside the radar transmit sector. Figure 23 shows good and bad choices for a given radar. In this installation, 
the radar transmit sector is [300º - 60 º], so a good choice for the target azimuth update is at the opposite 
end, or 180º.

Figure 23 – Good and Bad Choices for Radar Target Azimuth Update 
 
If the transmit sector covers the entire PPI area [0º - 360º], a good choice for the target azimuth update
 
is an 
azimuth angle at which few targets / intruders are expected. Generally, it is best to avoid setting
 
the target 
azimuth update at an azimuth aligned with a road. 
 
Once the target update azimuth angle is established, it must be set in the radar unit.
