TO DEVELOP AND DEMONSTRATE A DOPPLER RESOLUTION FILTER CONFIGURED AS A TAPPED DELAY LINE. The device will operate at a center frequency of 200 MHz and a 50 MHz 1 dB bandwidth. The Burst Processor Tapped Delay Line geometry will use a parallel channel approach such that each delay output is derived from a separate acoustic channel. The device employs double electrodes for both input and tapping output transducers the input consists of a simple, periodic transducer with six double electrodes, while the outputs use novel phase-reversal transducers with eleven electrodes. The BPTDL also uses a 300 MHz reference channel which directly measures the time delay and controls the insertion phase by means of a temperature control system. The delay line design has been thoroughly analyzed and experimentally tested. The photomask has been designed and ordered. Author
