摘要： A method and system for determining Psuedo-Noise (PN) composite phase is provided. The method includes providing at least three relatively prime PN component codes and partially correlating a received PN composite encoded signal with one of the PN component codes. The method also includes partially correlating the received PN composite encoded signal with a second one of the PN component codes while maintaining phase alignment of the first partially phase aligned PN code through the use of normalized autonomous phase numbers (NAPNs). The received PN composite encoded signal is then phase aligned with a receiver PN composite code phase in steps of epoch lengths of the partially phase aligned PN component codes.

摘要： Disclosed is a method, apparatus and a computer readable media that provide an ability for a first platform and a second platform to obtain information that is descriptive of a relative location of the other. The method includes establishing an initial antenna pointing direction of the first and second platforms such that the pointing directions are opposite one another, and incrementally scanning each antenna in azimuth in the same direction in synchronism with one another in a plane referenced to a common reference plane until each antenna is within the other antenna's azimuth and elevation beamwidth during a scanning increment dwell time (TDWELL). Upon completing a scan in azimuth in the plane, the method changes an elevation angle of each antenna pointing direction relative to the plane by equal and opposite amounts, and repeats the incremental scanning of each antenna in azimuth in the same direction.

摘要： A system for verifying composite pseudo-noise (PN) encoded signals. The system provides at least three PN component codes, wherein the at least three PN component codes are relatively prime. The system partially correlates a received PN composite encoded signal with a first minor epoch derived from the at least three PN component codes. The system searches for phase alignment of the received PN composite encoded signal with a second minor epoch derived from the at least three PN component codes. The system correlates the received PN composite encoded signal with a receiver PN composite code phase when the first minor epoch and the searched second minor epoch are separated by a predetermined phase.

摘要： A digital communication system includes a generator for generating a plurality of pulse trains, each having a different timing, and pre-compensation circuitry for synchronizing the plurality of pulse trains to a timing signal. The system also includes comparison circuitry for simultaneously comparing a received burst code signal to each of the plurality of pulse trains, where the burst code signal is synchronized to the timing signal, and a detector for detecting which of the pulse trains is a closest temporal match to the burst code signal. The pre-compensation circuitry operates to reduce acquisition time and keep PN code uncertainties within the range of the comparison circuitry.

摘要： An antenna positioned (with rough alignment) on an aircraft is calibrated in position and orientation relative to the inertial navigation system of the aircraft by measuring the corresponding position and orientation parameters of the aircraft and a reference target relative to the Global Positioning System (GPS) and calculating differences between azimuth and elevation parameters of the target measured by the antenna control system and corresponding roll, pitch and heading parameters measured by the aircraft system, thereby providing bias parameters for the antenna output in the coordinates of the inertial navigation system.
