The air traffic control radar beacon system ATCRBS was modified so as to eliminate false or second-time-around aircraft replies. A dual-channel stand-alone modification equipment unit was developed to stagger the beacon interrogations and destagger the reply video. The unit can be used with any beacon interrogator defruiter or processor. Two models, an analog and a digital, were developed. The resulting equipments were implemented and tested at the Bedford, Virginia, long-range radar facility. During the engineering tests and operational evaluation, the stagger modification performed reliably. It is recommended that the digital version be implemented at the field facilities.
