The AN/DKT-61A is a telemetry system which processes arming guidance, flight control and command data information of the AIM/RIM-7M/P anti-aircraft missile for 2.2 GHz radio transmission to receiving sites for recording, display and analysis. This functionality supports:

• Tracking of Sparrow, AIM/RIM-7M/P AAM by range.
• Data collection on in-flight missile performance.

General Performances

Information received and processed by the AN/DKT-61A from the missile comes from several sources including power, clock lines, synchronization signals, discrete and serial data, arming and guidance signals, flight control signals and fuse signals. The information is in the form of analog voltages, discrete voltage levels, digital signals, timing signals and video signals. Video signals and fuse signal oscillators modulate the transmitter directly, while the analog signals, discrete voltages and digital data are multiplexed and appear as a PCM signal on a voltage controlled oscillator (VCO) that also modulates the transmitter. Each PCM frame contain 128 bytes of data in a non-return to zero, low (NRZ-L) formatted with a three byte synchronization word, in accordance with IRIG 106-93.
