Actually, it's a lot harder than you think. The difference systems all process primary (RADAR) returns and secondary (IFF) differently. Some systems still in use today don't even have an ability to record.

I can give you examples from the different USAF surveillance platforms I crewed, USMC, USN, and many NATO systems I was lucky enough to use during exchange TDYs, and a handful of civilian systems I operated in Europe and Africa doing some very specific missions.

Tracking a known target in an automated environment is one thing. Detecting and tracking an unknown target is something else, identifying that unknown target is another thing altogether.

Depending on the rules in place, once IFF is lost, having a known ID of what a target used to be is no longer valid and, while educated guesses can be had, maneuvering of the target and/or loss of RADAR on the target may not even allow you to make that educated guess anymore.

Also, not to be picky, but how you are using specific terms doesn't really jive with how those terms/systems were used in the 14 or so years I did that.

I was working from the assumption that their PSR had playback capability and at no time was I suggesting tracking a primary target while in operation. I was thinking more along the line of tracking it during the playback.
Malaysia is after-all a first world country

This is a completely valid point

But given the time of day, altitude and speed, it's highly unlikely for it to be anything else

I don't know. When I was an AF controller in Altus OK (no traffic after midnight) we saw a lot of very strange primary returns on mid shifts. Good strong primary returns with target trails, two to five targets circling the same areas for hours. Often backed up with phone calls from concerned farmers.
 
Enjoying the free education on this thread. Thanks to those of you sharing the knowledge. Here's my own small contribution since I work in the telecommunications industry:

@ChasenSFO since he asked the question originally about the claims of the cellphone ringing from the passengers...

Ringback is meaningless.

The ringing sound you hear on any phone call is called ringback tone. Typically, you will hear ringback cycles and then voicemail. In the case of voicemail with cell phones, the voicemail system and the handset are separate entities. So when you ring someone and get a few rings, you'll get a couple additional when it's going to voicemail. That 1-2 ring cycle is really telling you that the voicemail server has your call, and it's busy grabbing an available audio port for you to connect to so it can play the user's greeting or whatever.

Ringback is there purely for psychological effect. You don't actually need it to do anything. Up through the 80s, various systems could "hear" ringback on the line and used it as signal detection to do various things...these days, the signaling in the call is done digitally. There is no actual need at all for dial tone or ringback - it's merely for your comfort/expectation as a subscriber.

Whether or not you hear ringback is only an indication that the carrier is or is not providing it during attempts to set up a call and/or transfer it. It has ZERO - absolutely ZERO - bearing on whether or not a handset is active. It is meaningless.
 
I would like to propose that we all STFU about users we don't align with.

Thank you; it's a big-enough world that we can generally get away with ignoring things we don't like. There's even a feature of the XenForo software to assist with that.
 
Back to the investigation....

Unconfirmed reports of a body found wearing an MH lifejacked in the Malacca strait.

--------
The Beijing News has reported that a source claiming to be local volunteer assisting in the search for missing Malaysia Airlines flight MH370 has found a dead body wearing a lifejacket in an area of the Malacca Strait. In a single-paragraph report, the website of the Chinese-language newspaper said that it was seeking to establish the reliability of the claim.

The unconfirmed report is said to have come via a new operations center established in Malacca after the search for the flight was expanded to both sides of the Malaysian peninsula in response to reports that the plane may have diverted from its planned course. The report was first passed to the center of operations for search and rescue efforts on Vietnam's Phu Quoc island.

The last contact with the plane placed it over the South China Sea on its scheduled course from Kuala Lumpur to Beijing.

The Boeing 777-200 with 239 people aboard took off early on the morning of March 8. It disappeared about an hour into the flight with no distress signal or message sent.

^^ plot twist.

I hope that searching in the wrong area didn't cost people their lives. Imagine if the plane did in fact go down in the see without a break up and there were survivors floating around waiting for rescuers. Yikes! :(

Dont even talk about it. Terrifying possibility. That being said, the pax would have been wearing life jackets anyway if they knew they were having a water landing?
 
Also being reported are that fisherman have found a life raft, but it sunk during transfer to the navy...not sure how that happens, but there it is. (Also in the Malacca Strait)

That's true. If they knew they were going down and had time then the flight attendants would have instructed them to put the life vests on.
