This book was released on 1960 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: Progress on the ultrasonic delay line research task is presented. An extension of the evaporation bonding technique with indium to include the application of indium backings is described. Experimental results obtained for the bandwidth and reflection coefficient of an AC cut quartz transducer and a delay medium of fused quartz are compared to theory. The initial results obtained using lead as a bonding and backing material are described. Techniques employed to bond with lead and the initial experimental results obtained are presented, and a significant improvement over the results achieved with indium is indicated. Theoretical results indicate further improvement when the bonding techniques used for lead are refined. Results of an investigation of the diffraction effects due to a rectangular transducer are presented. An experimental apparatus used to measure diffraction effects with a dynamic range in excess of 50 db is described. Results of a series of measurements on a bonded transducer indicate the transducer vibrates with essentially constant amplitude, with minor variations due to the bonding process. (Author).

This book was released on 1979 with total page 42 pages. Available in PDF, EPUB and Kindle. Book excerpt: Radar cross section measurements were made on Teledyne Micronetics' Radar Range using C-band one nanosecond pulses. The radar target was made up of retrodirective Luneberg lenses variously deployed on a turntable. The number of lenses varied from two to six. For each deployment of targets, the impulse response was experimentally determined with the help of a sampling scope and the complex conjugate of this impulse response was synthesized using power splitters and delay lines. This signal was then transmitted and the RCS enhancement was measured by reducing the level of the transmitted power until the maximum response was equal to a previously established reference level. Subsequently additional power splitters and delay lines were utilized to synthesize matched receiver response and a similar comparison technique was used to measure the increase in the RCS. The configurations which were tried included equal and unequal spacings and path geometries where the individual reflecting centers were separable and cases where they overlapped. The observed value of RCS enhancement were compared with the theoretical values and it was demonstrated that the agreement between the two values was in general well within one dB. (Author).
