I don't want to track the drone, I want to track these (Transmitters), could I do it with Arduino please?
1- Is that a spreadspectrum transmitter ?
2- What do you mean by "track" ? (transmitters don't move)
Do you mean "monitor" ?
In Canada our forest fire firefighter's are being hampered by drones. Drones are like dogs, there are no bad ones, just bad owners.
We need to find who is holding the transmitter. Even if a drone is in autonomous mode, most RC's still have their TX on for a manual failsafe. Could I find a transmitter, or piggyback the feed to the intruders video camera using Arduino, please?

If it's spread spectrum I don't know if you can triangulate on it. In order to do that you would need 3 signal strength monitors. I don't know enough about spread spectrum . I would just shoot the drones down with a shotgun. The buckshot won't travel very far.
ROFL...rasch, no matter who I ask for guidance, quadcopter forum, raspberry pi forum, ham radio forum's...they ALL grab their shotguns...you guy's are too funny!!
Someone told me I need a spread spectrum analyser, but I don't know how to extract the transmitter location from it?
If I locked on to the signal, wouldn't the signal get stronger as my patrol drone got nearer (without trianguating)? A less lethal approach...lol.
Are the drones flying low enough to hit with the water hose ?
I would use a GPS to locate my position with respect to the drone and then a compass to locate my position with reference to the drone. I would transmit on a radio "My coords are xxxxx-xxx--xxxxx and the target is 100 m NW of me. Someone else can get 30 degree off from you , and a third person 30 degrees off from them. When you are all in position , aim your shotguns and fire... The spent buckshot will fall harmlessly between the three shooters. Use 12 gauge birdshot.
Google, "drones and forest fires", they are really becoming a problem for our first responders!
Screw it. Just call SWAT.
They don't have one yet, hence the question.
I don't know how to jam spread spectrum.
James Coliz, Jr. maniacbug@ymail.com has produced a library (maniacbug-RF24-e1527af, better known as 'RF24') for use with Nordic NRF24L01 transceiver boards. With this lib is an example 'Scanner' which detects activity in the 2.4GHz band used by that device (and quite a few RC Transmitter/Receiver combos used with drones). A NRF24L01, with LNA and RF-
amp and antenna (with the antenna replaced by a high gain directional antenna) attached to an UNO, running the Scanner example 'COULD' be used to detect activity in the presence of an unidentified drone. Directional antenna would give crude directional bearing, multiple sets could be used to, roughly, triangulate transmitter source. best high gain design found, so far, uses a reflector (like a metal pie plate) and two diamond shaped elements about 4 inches on a side. Google search will turn up design and construction details. NOT SUITABLE for drone deployment. you'll have to have a ground crew running the detection and tracking. Yes, the RC transmitters ARE spread spectrum, so you will have to scan all channels while tracking. will not be very accurate or close tolerance, but could work, in theory. Best source for the NRF24L01 board is 'http://yourduino.com' :: 2.4GHz Transceiver w/ Power Amp +PreAmp nRF24L01+ SKU: RA-030403,
Sale Price: $13.50
By the time you get this put together and sorted out, the fires will either be out, or have devoured everything in sight. A single firefighter with a 28 guage shotgun would still be your best bet, make sure the water bombers are out of the area, which they will be, and take one or two down, word will get around and the idiots will stop risking their $1,000+ quads for a you-tube submission... With NO additional hazard presented to fire service personnel.

Did the person giving you advice know its on a drone ?
They are rather big and heavy.
Signal strength is not a good guide of direction.
RDF is best done by having 2 ground stations with directional aerials to triangulate the position of the tx.
Using drones for this could work but without CIA funding is likely to be impractical.
Using a directional aerial atop a long pole or pneumatic mast (like realtor's use to take photos)
is probably a simpler solution
Edit, if you use signal strength to home in on the strongest signal it likely to come straight at you as you being the controller are likely to have the strongest signal.
I think you are confused. The OP is not asking how to use drones to track drones. He's asking us how to LOCATE the transmitter (operator) of the drone so he can be arrested or cited. As I already mentioned, normally, the transmitter doesn't move so the objective is to LOCATE (NOT track) the transmitter controlling the drone.
I don't see why the drones are a problem. Why can't you just ignore them ?
How are they "getting in the way" ?
What do you plan to do once you locate the operator (transmitter) ?

Yes i understand that .
BUT he is using a drone to find the strongest transmitter scource.
That is likely to be the transmitter he is using to control his searcher drone.
You could run a 2.4 Ghz signal jammer with a yagi attennae and "shoot" it out of the sky. The owner will come to you asking for their $1k drone. No need to triangulate 
I think that blasting a lot of RF at them would knock them down. Im sure with time the manufacturers of drones will include a failsafe OFF that lea can use to knock drones out of the sky.
BUT he is using a drone to find the strongest transmitter scource.
No, he is NOT using a drone. He is complaining that the drones interfere with firefighting. Why in the world would he say that and then use one himself. Does that make ANY sense ?
If they're in the way, a well-aimed hose or shotgun is soon going to deter them.
Yes, the OP says he has received dozens of shotgun recommendations.

They can ask all they want. They will be cited for intering with Emergency Services and they won't get any reimbursement because their drone has been confiscated by the county for posing a hazard to the firefighting crew.
Boardburner2 is correct, I am going to use the "forces of good" drone, to rid the "forces of evil" drone's from the fire zone. I have included a map of the fire zone, and the restricted area around it. And put your shotgun's away guy's (and gal's), as you can see in the map the fire was VERY close to wiping out a small community. To many houses and property (people were evact'ed out) to use the fun 12 gauge way of drone suppression.
I really want to avoid jamming because of all the communications amongst the rescuer's, police, ambulance, etc..etc. Not to mention the guy with a pace maker...lol.
I have found a spread spectrum analyser that is small enough, and almost light enough to connect to my drone. If I could receive the information wirelessly from it (on the ground) I could phone my ground crew (brother with a $700 car...lol) and give him a direction. If I flew towards the signal, it would get stronger wouldn't it.
123Splat gave me a TON of good info (I think). I am going to spend the rest of my night trying to learn what in the world he is talking about..lol...and I love it!
Here is the actual restricted zone issued to the public.

????
HOW ?
