Systems and methods for guiding an object may comprise improved guidance laws that improve the effectiveness of the PRONAV guidance law. The improved guidance laws may utilize the same parameters as the PRONAV law and may be algorithmically simpler than conventional guidance laws bec
An improved process and apparatus for measuring performance characteristics of microwave power components. The invention involves the use of a rotating phase reference technique to improve measurement. The process and apparatus result in fast, accurate, reproducible determination of the
A canceler loop is used to provide negative feedback to a crystal oscillator to reduce the effects of shock and vibration on the spectral purity of the crystal oscillator. The canceler loop demodulates the output of the crystal oscillator and supplied a stabilizing voltage representa
A method and apparatus to determine angles .theta..sub.1 and .theta..sub.2 between paths of two sets of reflected radar waves and a radar boresight utilizes the electrical angles .beta..sub.1 or .beta..sub.2 and two successive radar target observations. One set of radar waves may travel
In a system for reducing sidelobes in adaptive receiving array antennas, an auxiliary signal is radiated through an omnidirectional antenna collocated with the phase center of an adaptive array antenna. The auxiliary signal is so transmited as to form a probe or pilot beam with a notch i
