Erfasst hätten die Awacs-Aufklärer zudem „Signale von einem Flugabwehrraketensystem sowie ein weiteres durch Awacs nicht zuzuordnendes Radarsignal“. Das Flugabwehrsystem sei automatisiert als „Surface to Air-Missile“ SA-3 klassifiziert worden, „ein in der gesamten Region routinemäßig erfasstes Signal“.
that 2 NATO AWACS picked up radar signals of a SA-3 system and another unidentified signal before they lost MH17.
They would know what the signature denotes. That they claim its unidentified is the smoking gun, imo. Not ground missile radar.
EHM uses a range of sensors strategically positioned throughout the engine to record key technical parameters several times each flight. The EHM sensors in aero engines monitor numerous critical engine characteristics such as temperatures, pressures, speeds, flows and vibration levels to ensure they are within known tolerances and to highlight when they are not.
A critical aspect of the EHM system is the transfer of data from aircraft to ground. Aircraft Communications Addressing and Reporting System (ACARS) digital data-link systems are used as the primary method of communication. This transmits the Aircraft Condition Monitoring System (ACMS ) reports via a VHF radio or satellite link whilst the aircraft is in-flight.

i.e.; they do not know which side was operating the system.
