@TheInsider F-22 radar can see radar signals of all the F-35s flying below it through R modules while in passive mode without transmitting anything even when F-35 AESA (most modern hard to detect) are targeting other planes. Similar to Sentinel satellites seeing Sx00 radar signals from all the way from space but better since this is AESA.
This method is similar to submarines rarely sending a sonar ping and running sonar silent for days while constantly listening for enemy pings.
Will BURFIS receiver modules be able to scan the sky for enemy AESA radar signals and channel hopping encrypted communications even when they are not directed at KAAN?
Submarines can send a single pulse instead of max power continuous waves to detect other silent running submarines. Can KAAN do that single ping tactic against a silent F22?
