Abstract
1353801 Dispersive delay lines; pulse radar TEXAS INSTRUMENTS Inc 5 Aug 1971 [26 Aug 1970] 36869/71 Headings H3U and H4D A pulse, comprising a waveform which sweeps linearly or otherwise from a minimum to a maximum frequency or vice-versa as it is produced, Fig. 2 (not shown), and which may also be shaped in amplitude, or divided up into further sub-pulses during the frequency sweep, is applied to a frequency dispersive acoustic surface wave delay device which delays the pulse by at least its duration and compresses its time duration, Fig. 3 (not shown). As shown in Fig. 1 a single crystalline prize substrate 14, of lithium niobate, quartz, zinc oxide or cadmium sulphide supports broadband input transducers 15, 19, 23 and output transducers 17, 21, 25, which may be uni- or bi-directional, belonging to respective sections 10, 11, 12, series connected. Frequency dispersive arrays 16, 20, 24 have interdigitated electrodes so spaced that, at the instant when the initial low frequency portion of the pulse provided by source 46 reaches electrodes 49, 51 of array 24, the last, high frequency pulse portion has just reached electrodes 36, 37 of array 24, and the electrode spacing throughout the arrays 16, 20, 24 is matched to the instantaneous wavelength of the surface waves passing, being one half the corresponding instantaneous wavelength, so that a high amplitude spike (32), Fig. 3 (not shown), appears at the delay device output A, A
