TAPPED DELAY LINE SYNTHESIS OF LARGE TIME BANDWIDTH SIGNALS
Abstract
A method is presented for linearly generating large time-bandwidth signals by tapped delay line filter synthesis techniques. The method is de veloped by an example wherein a filter with a constant amplitude and linear time delay transfer function of arbitrary time-bandwidth product is synthesized. Special emphasis is placed on equipment simplicity and ease of implementation. The essential elements employed by the technique are quartz delay lines, bandpass filters, band pass phase shifters and resistive weighting net works. The techniqu1es not make use of many elements which are found in most conventional pulse compression systems. In particular, dis persive networks, mixers, frequency synthesizers, and precision bandpass filters are not required. Consequently, the total number of components is small, even for time-bandwidth products of a few thousand, thereby making it feasible to obtain good peak signal to 'hash' sidelobe levels at the matched filter output.
