Abstract : A multichannel data acquisition and retrieval system developed for a recent program has provided an effective means of documenting field tests of an experimental airborne radar system. The system provided transducers to sample a variety of experimental, environmental, and radar system parameters. Using conventional telemetry techniques the system stores and recovers the various parameters and 'voice log' from a restricted bandpass record channel. As a consequence of the techniques employed, the system provides a means of simultaneously documenting radar video recorded by an AMPEX AR-500 airborne video recorder during field tests through the use of its auxiliary record channel. In addition, the system provides a reliable and convenient display of the recovered parameters during the subsequent analysis of field tests by NRL personnel. Finally, the system can be readily adapted to new documentation requirements.
