The method including: providing reference signals from RF reference sources to illuminate RF sensors on the moving object; positioning the RF reference sources to form a reference coordinate system; determining position information designating a position of the target in the reference coordinate system by a forward observer; fixing at least one of the RF reference sources at the forward observer in the reference coordinate system; determining a position and orientation of the moving object in the reference coordinate system on board the moving object based on signals received at the RF sensors from the RF reference sources and based on the positions of the RF reference sources; and guiding the moving object to the target at least based on the determined position and orientation of the moving object and the determined position information of the designated target. | 11-25-2010 |
20120169524 | SINGLE CHANNEL SEMI-ACTIVE RADAR SEEKER - The disclosed approach provides a low-cost approach by employing a single channel receiver for a direction-finding missile, rather than a conventional four-channel system. It employs interferometry techniques. The proposed approach leverages orthogonal waveforms and pseudorandom noise (PN) codes. This is a low-cost approach for a single channel direction finding system by leveraging orthogonal waveforms and interferometric techniques. | 07-05-2012 |
20120200449 | ADAPTIVE ELECTRONICALLY STEERABLE ARRAY (AESA) SYSTEM FOR MULTI-BAND AND MULTI-APERTURE OPERATION AND METHOD FOR MAINTAINING DATA LINKS WITH ONE OR MORE STATIONS IN DIFFERENT FREQUENCY BANDS - Embodiments of an adaptive electronically steerable array (AESA) system suitable for use on a vehicle and method for communicating are generally described herein. In some embodiments, the AESA system includes a plurality of arrays of radiating elements and control circuitry to configure the arrays for multi-band and multi-aperture operations to maintain data links with communication stations. | 08-09-2012 |
20120249358 | DYNAMIC CALIBRATION RADAR SYSTEM - A missile radar system includes a tapered radome covering a front face of a main antenna. A calibration antenna is the combination of a metal tip and an attached one or more radiating or excitation elements (monopole) on the tip. A narrow end (wedge) of the radome may aid in directing planar calibration waves toward the main antenna. The metal tip has a curved inner surface that acts, with the attached radiating element(s), as an aperture antenna. Signals are emitted from the calibration antenna back toward the front face of the main antenna. The signals pass from the tip/reflector to the front face of the main antenna through a substantially-metal-free and substantially-dielectric-free volume defined by the inner surface of the radome. The radar system allows for calibration of the antenna prior to launch and/or during flight of the missile. | 10-04-2012 |
20120268309 | VIRTUAL APERTURE RADAR (VAR) IMAGING - Virtual Aperture Radar (VAR) imaging provides terminal phase radar imaging for an airborne weapon that can resolve multiple closely-spaced or highly correlated scatterers on a given target with a single pulse to provide an aimpoint update at a useful range to target without training data and without requiring a large aperture antenna. VAR imaging exploits the sparse, dominant-scatterer nature of man-made targets. The array manifold is constructed with a large number of basis functions that are parameterized by range or angle (or both) to target. The number of basis functions extends the capability to resolve scatterers beyond the Rayleigh resolution. However, this also makes the manifold underdetermined. A sparse reconstruction technique that places a sparsity constraint on the number of scatterers is used to solve the manifold to uniquely identify the ranges or angles to the scatterers on the target. These updates are passed to the weapon's guidance system, which in turn generates command signals to actuate aerodynamic surfaces such as fins or canards to steer the weapon to the target. | 10-25-2012 |
