Abstract

In an attempt to improve a pulse compression filter using a fused quartz rod, we devised a method to eliminate an unwanted L (0, 2) signal over a wide frequency range and, at the same time, obtain sufficient time dispersion. We found that the suppression of the L (0, 2) unwanted signal is realized using the freouency band where the change of patterns of L (0, 2) and L (0, 3) modes is slight. Sufficient time dispersion is obtained using a tapered cylindrical fused quartz rod.
