Abstract :
A doppler resolution filter is described which utilizes two acoustic-surface-wave tapped delay lines to perform an important RADAR signal processing function. The (-1 dB) bandwidth is 50 MHz and the delay increment for each tap is 5.0 mu sec, for a total of 16 taps. A novel LiNbO/sub 3/ temperature stabilization technique is reported for controlling the 80 mu sec delay line stability to /spl plusmn/2 x 10/sup -7/ over an ambient 10/spl deg/F range.
