Abstract : In order to evaluate the effects of ATCRBS interference on the design of a Discrete Address Beacon System (DABS) sensor, a simulation program was developed. A detailed model of the sensor is presented taht takes into account many of the antenna pattern and signal processing design parameters. A model for the fruit generator is developed so that reply processor performance in typical 1980 high density fruit environments can be evaluated. A particular reply processing algorithm is adopted as a baseline to decode DABS messages and produce a data edited azimuth estimate, so that the design methodology can be illustrated. Statistics characterizing the reliability of the processor are computed as a function of fruit rate and signalling conditions. The simulation is an invaluable tool for performing sensor/reply processor tradeoff studies. (Author)
