A TECHNIQUE FOR SYNTHESIZING SIGNALS AND THEIR MATCHED FILTERS

Abstract

A nonuniformly tapped delay line is the key component in a device that can be used both to generate an arbitrary waveform and to act as a matched filter for this same waveform. Formulas for calculating the tap delays and weights needed to generate a given waveform are derived. The effects of delay- line attenuation and a technique for compensating for these effects are discussed. An experimental system embodying these design techniques is described. This system generates and receives a linear FM waveform of 0.5- microsecond duration and either 200- or 400-MHz bandwidth. Construction details and the results of many tests run on the system are given.
