As for the automated command and control system which might be deployed to Syria, my guess is that the Polyana D4M1 would be a prime candidate. Whatever the actual mix will be in the end, I would argue that this presents a more formidable capability than additional S-300 launchers. Sure, this is apples and oranges, but we have to keep in mind that these electronic warfare systems are extremely powerful force-multipliers which can dramatically increase both the Russian and the Syrian defensive capabilities by jamming GPS signals, datalinks, cellphone signals (used for targeting and intelligence), radars, by creating false targets and even by destroying electronics. Electronic warfare is one field in which the Israelis have always enjoyed a huge superiority over their Arab victims and the fact that this has now changed is an extremely distressing development for them, even if they will never admit it.
Presently, the cell phone jammer devices are becoming civilian products rather than electronic warfare devices, since with the increasing number of the mobile phone users the need to disable mobile phones in specific places where the ringing of cell phone would be disruptive has increased. These places include worship places, university lecture rooms, libraries, concert halls, meeting rooms, and other places where silence is appreciated.
The S-400 air defense system is reportedly capable of engaging up to 36 targets simultaneously. It can purportedly fire missiles at a rate 2.5 times faster than its predecessor, the S-300, and can engage stand-off jammer aircraft, Airborne Warning and Control System (AWACS) aircraft, and both ballistic and cruise missiles.
Instead, you can use protocol mixing and RC manipulation to be able to pinpoint exactly the drone that you need, and turn it on or off, or send it home, or make it under your control.
Will a can of mud or paint thrown at the cameras sensors, and/or an rf signal jammer cause the driverless trucks to drive off the road?Be really hilarious* if it were remotely hackable, and supply trucks just drove away.* not remotely hilarious if you depended on the supplies of course.
A cellular phone is a full-duplex device that utilises two frequencies at the same time. One is for talking while the other is for listening. The signals are handled at the same time. There are signal jammers that can only block one of the frequencies at a time, which results to the blocking of both because the phone thinks that there is no service in the area because it can only get one of the frequencies.
