A LINEAR FM 1000:1 PULSE COMPRESSION SYSTEM,
Abstract
A linear-FM pulse compression system, synthesized as a linear time-invariant filter, is described. The transmitted waveform is roughly rectangular in shape, has a bandwidth of 1 mc, and has a duration of one millisecond; the output of the matched-filter receiver is consequently (sin x)/x in shape (before side-lobe reduction) and has a duration of about two microseconds from null to null. The parameters are thus directly compat ible with long-pulse space surveillance radars. The system contains both allpass networks and quartz delay lines. Ten channels, each control ling one-tenth of the output waveform are arranged in the form of a tapped delay line with one dispersive network connected to each tap. A brief discussion of the theory of the system, the preliminary experimental bench-test results, and a section on the practical problems encountered in the construction of the filter and its asso ciated equipment are presented.
