Abstract: The present disclosure provides for bulk depolymerization of polymers at significantly lower temperatures than possible through currently available methods. The present disclosure provides for polymers and modified polymers that include at least one thermolytically labile end-group.

Abstract: The present invention provides a method and apparatus for effecting, in a ssive manner, the acquisitioning of a broadband barrage jammer type radar target, by detecting the differential delay between the barrage signal as received at a predetermined location over direct and indirect paths and producing a signal distinctly identifying the location of the jammer target relative to the receiving station. More specifically, the present invention includes means for generating reference pulses of varying frequency which are utilized in determining the phase relationship which exists between each of these reference pulses and the corresponding frequency component of the jammer signal as received over the direct path to the target.

Abstract: A hybrid digital-optical radar signal processor utilizing electro-optic ctals and having no moving parts. The processor is used with a radar having multiple discrete evenly spaced transmit frequencies, generated in a pattern, and is capable of simultaneously processing information relating to multiple targets. In the receiver section of the radar electro-optic crystals, such as Lithium Tantalate (LiTaO.sub.3), act as optical phase shifters and are arranged in a data plane which is illuminated by a CW laser. Provision is made in digital delays and the optical phase shifters to provide flexibility in the selection of the pattern of frequency utilization during the transmit period. The optical output of the processor consists of an illumination pattern in a read-out plane with maximum intensity in said plane at positions corresponding to the velocity and fine range of each target.
