Interference Reduction Techniques Study-Radar.

摘要

The report summarizes the findings of the initial phase of study, the final phase, and the results, conclusions, and recommendations derived therein. The purpose of the Interference Reduction Techniques Study is to develop procedures or techniques which reduce the amount of electromagnetic interference produced by state-of-the-art radar systems. In this study the theory of binomial pulses is used to derive the minimum 80 dB bandwidth pulse which has a minimum effective bandwidth requirement. This result is extended to meet a physical requirement of a peak power limitation. The theory of composite binomials is thus established. Within the phase two program, state-of-the-art transmitter techniques are explored and concluded that specially shaped pulses can be used as high power waveform configurations. The study concludes with the definition, quantity, and prediction of interference inherent in the radar system, and the feasibility of implementing minimum bandwidth design procedures at the conceptual design level.
