False Radar Mitigation

Who needs it

If you are using DFS frequency bands 5.3/5.4 GHz FCC and 5.4/5.8GHz ETSI you should use
this facility.

DFS and False Radar Mitigation

About DFS
Under DFS frequency bands, it must be ensured that radio links do not interfere with certain
radar systems in the 5 GHz band. If radar is detected, the radio link should move automati-
cally to a frequency that does not interfere with the detected radar.
What is False Radar Mitigation
False Radar Mitigation capability is an advanced method to reduce or eliminate false radar
detection and DFS triggering ("False positives").
False radar detection can be caused by other radios transmissions or external interference
that can be interpreted as true radar.
This option is active only in DFS frequency bands, 5.3/5.4 GHz FCC (HBS only) and 5.4/
5.8GHz ETSI (HBS & HSU).
In what follows false radar means any source of radar-like signals which are not real radar.
False Radar Mitigation has two components:
1. Reduction of false positive radar detection by reduction of the probability of detecting any
kind of false radars, while allowing the system to detect real radar signals.
2. Elimination of detection of specific false radar types by blocking detection of false radars of
a specific type. There are three types of radars:
• Fixed: False radars with fixed pulse width having fixed repetition frequency
• Variable: False radars with variable pulse width having variable repetition fre-
