Abstract
A collision-predictive CAS at a protected station or vehicle that produces TAU data relating to differential azimuth and/or TOA from standard ATCRBS interrogations and replies, and selects the largest closing TAU signal of a threatening Other station to provide reliable warning while minimizing false alarms. Similarly processed differential altitude information provides a further criterion. Multiple radar environments enable production of additional sets of TAU values and increased discrimination against false alarms.
