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 method and system is disclosed for generating and detecting variable sequence PN codes. PN-Code sequence changes based on varying interceptor threat levels are generated at a rate fast enough to avoid exploitation while maintaining a reasonable correlation search window. The PN code sequence is phase shifted by N-chips based on the severity of the threat environment. A synchronized receiver demodulates the PN encoded signal by correlating over every possible phase of the PN code sequence. The receiver includes first and second correlators and threshold detectors adapted to detect PN signals with varying PN code sequence changes.

摘要： A method is disclosed for directing an antenna mounted in a restricted radome on an aircraft. The method can include the operation of determining whether the antenna is directed in a keyhole. A further operation can involve controlling the antenna using an elevation gimbal and an azimuth gimbal when it is determined the antenna is directed outside the keyhole. Another operation can include directing the antenna using an elevation, azimuth, and cross elevation gimbal when it is determined the antenna is pointing in the keyhole.
