INTERFERENCE REDUCTION TECHNIQUES STUDY.
Abstract
The objective of the Interference Reduction Techniques Study is to determine the minimum transmitted power and bandwidth required for the radar to meet its multiple system performance requirements. This mapping of performance requirements into required power and bandwidth may then be used to create design guidelines for constraining the allowable power and bandwidth of new radars. A survey of electromagnetic compatibility specifications and standards was conducted to determine present and past methods of establishing electromagnetic compatibility (EMC) control criteria. The direct performance parameters of range accuracy, range resolution, velocity accuracy, and velocity resolution were selected for the initial establishment of required design parameters. Using the perfect processor philosophy, the range accuracy and resolution, and velocity accuracy and resolution were related to the received signal-to-noise power ratio, rise time of the leading edge of the signal, and dwell time of the signal. The binomial pulse (whose waveshape may be approximated by a gaussian form) is widely recognized for its narrow band spectrum. This specific waveform was used with the generalized performance parameter-to-design parameter relationships to derive the minimum 80 db bandwidth necessary to meet each of the radar direct performance parameter requirements under the assumption of 'perfect signal processing'. Four equations for greatest lower bound of 80 dB bandwidth are thus identified as the departure point for the remainder of the study.
