The report summarizes the results and preliminary conclusions derived from the field acceptance test of feasibility model airborne TimeFrequency Collision Avoidance System equipment. The equipment described includes general aviation-type MiniCAS units which employ time differenced range measurements deltaRdeltaT to digitally derive range rate. Special deltaRdeltaT units, which interface with aircarrier type CAS, were also tested to obtain simultaneous comparison of Doppler-derived range rate with deltaRdeltaT. Both versions of the airborne CAS employed full TAU-threat evaluation logic. Preliminary results indicate that the newer deltaRdeltaT logic provides better range rate accuracy than the original Doppler method. The report includes analyses of communication reliability, time synchronization accuracy, range rate accuracy and CAS-threat response for a limited sample of acceptance test data.
