Kenneth J Campbell: RF signal generator. The United States of America represented by the Secretary of the Navy, R S Sciascia, G J Rubens, T M Phillips, September 6, 1977: US04047121 (92 worldwide citation)

An RF test signal generator including a driving oscillator, a pulse generr for generating narrow spikes at the oscillator frequency (such as a step recovery diode), a modulator and an attenuator. Since the very narrow pulse exhibits nearly constant amplitude in the frequency domain, a constant ampli ...

Kenneth J Campbell: FM RF signal generator using step recovery diode. The United States of America represented by the Secretary of the Navy, R S Sciascia, G J Rubens, T M Phillips, March 22, 1977: US04013966 (89 worldwide citation)

A step recovery diode pulse generator is driven by a fixed frequency oscitor to provide pulses which are modulated in a balanced modulator by means of a voltage controlled oscillator controlled by a variable frequency input. The output of the balanced modulator is attenuated and provides a frequency ...

Maurice Leon Schiff: Spread spectrum modem. The United States of America represented by the Secretary of the Navy, R S Sciascia, G J Rubens, H Fendelman, January 20, 1976: US03934203 (51 worldwide citation)

Digital data having a rate R and to be transmitted is converted into a K- code, T-seconds long and delayed according to a particular N-bit word, where N=RT, whereby the code carries information in its delayed position in the T frame and not in the code itself. At a receiver station, the correlation ...

Albert Roth: Digital correlator. The United States of America represented by the Secretary of the Navy, R S Sciascia, G J Rubens, T M Phillips, June 28, 1977: US04032885 (50 worldwide citation)

A digital correlator which will detect a digital pattern in the presence of noise. In an n bit pseudo-noise (PN) sequence, comparison is made of the input word with m desired PN coded word patterns; a flag is raised when a pattern is detected and identified. In one embodiment all possible (six) PN c ...

Henry F Taylor: Passive frequency-selective optical coupler. The United States of America represented by the Secretary of the Navy, R S Sciascia, G J Rubens, J W McLaren, May 18, 1976: US03957341 (42 worldwide citation)

A passive frequency-selective optical coupler comprises first and second dielectric waveguides disposed in proximate (preferably parallel) spatial disposition relative to each other. A phase propagation constant at a known frequency is common to guided modes of both dielectric waveguides while the p ...
