System analysis was performed in the areas of digital filter design for performing clutter synthesis and real-time software for processing prerecorded target signals. In preparation for hardware implementation, circuit board standards have been determined and a circuit information program was developed to be used as an aid in deriving cost and schedule requirements for hardware implementation. As a result of the digital filter analysis, a two-pole filter has been selected which provides the variety and flexibility needed to synthesize ground clutter. An investigation of quantization indicates that 16-bit arithmetic will be needed during the filters computation. The major computational burden imposed upon the real-time software is the processing of prerecorded data coupled with the computation of antenna gain. Timing analyses indicate that the antenna gain multiplications should be performed in the EROS digital processor, that provision is needed for blocking the output target data to the EROS digital processor, and that the number of simulated targets be restricted to one or two. Two 2-target simulation modes and one 1-target simulation mode are described.
