PULSE COMPRESSION OPTICAL RANGING STUDIES.

Abstract

Progress on the optical/ultrasonic pulse compressor experimental breadboard is discussed. The major part of this period's effort has been devoted to optical correlation and pulse expansion. The highlights of this reporting period are: Improved diffusion layer transducers have been fabricated. Pulse encoding and expansion with a CdS-quartz ULM at 120 Mc has been obtained. Progress has been made on the pulse expansion-compression loop. The difference between pulse integration and the integration of the correlation process is explained in the system analysis. A practical comparison between a pulsed laser radar and a continuous wave (cw) laser radar is shown. A digest of the signal-tonoise advantage of pulse compression is given. A report on the effects of atmospheric attenuation is also included. (Author)
