Refer to Table 9 and
Table 10
Table 8 – R1, R2, R3, R3D, R5 and R5D Radar Assemblies Synchronization Method
The R1, R2, R3 and R3D radars operate in the same frequency band. Similarly, the R5 and R5D also
operate in the same frequency band, however they use a different band than the R1, R2, R3 and R3D.
Therefore any R1, R2, R3 or R3D does not interfere with a R5 or R5D. The chirp slots of these two
frequency groups can be setup separately.
A unique chirp slot must be assigned to each radar assembly at a given site and within the same
frequency group. Chirp slots correspond to transmission resources. When many radars transmit on the
same site, they will not interfere with one another if they use different chirp slots, as described in
Table 9 and Table 10.
If the number of radars exceeds the quantity of available chirp slots, chirp slot values may be reused if
the following conditions are met:
1. Their transmission sectors are defined so that they do not transmit towards each other.
2. They are separated by a distance at least greater than the radar range.
Figure 25 shows an example of a system where 2 radars are both using chirp slot 0.
