摘要： A spatially-distributed architecture (SDA) of antennas transmits respective uniquely coded signals. A first receiver having a known position in a coordinate system defined by the SDA receives reflected versions of the uniquely coded signals. A first processor receives the reflected versions of the uniquely coded signals and identifies a position of a non-cooperative object in the coordinate system. A platform with a platform receiver receives non-reflected versions of the uniquely coded signals. The platform determines a position of the platform in the coordinate system. In an example, the platform uses a self-determined position and a position of the non-cooperative object communicated from the SDA to navigate or guide the platform relative to the non-cooperative object. In another example, the platform uses a self-determined position and information from an alternative signal source in a second coordinate system to guide the platform. Guidance solutions may be generated in either coordinate system.

摘要： A system includes a set of spatially separated transmit antenna elements (SSTAE) broadcasting uniquely identifiable waveforms, a set of spatially separated receive antenna elements (SSRAE) and at least one circuit assembly. The at least one circuit assembly is electrically coupled to the SSRAE, which provide respective electrical signals responsive to the uniquely identifiable waveforms. The electrical signals include at least one target signal and electromagnetic interference. The circuit assembly operates on the electrical signals to create a matched projection space parallel to a reference related to the at least one target signal and a second projection space that is orthogonal or nearly orthogonal to the matched projection space. The second projection space includes the electromagnetic interference but not the at least one target signal. The circuit assembly uses the second projection space and the matched projection space to separate the electromagnetic interference from the at least one target signal.

摘要： An adaptive parameter for adjusting a threshold in a sensor system that provides a constant false alarm rate is disclosed. A projection space generator performs projection operations to create a matched projection space and first and second mismatched projection spaces such that each mismatched projection space is orthogonal or nearly orthogonal to the matched projection space. A mitigation engine receives the matched and first mismatched projection spaces and generates a set of weights from one of the first mismatched projection space or both of the matched and first mismatched projection spaces. A second mismatched projection space that is mismatched to both the matched and first mismatched projection spaces is provided to a clutter characterization engine that generates samples from the second mismatched projection space and the set of weights. The adaptive parameter is generated from the samples and is used as an input to a threshold adjuster in a target detector.

摘要： Systems and methods are provided for mitigating natural and man-made interference through the use of one or more orthogonal, or nearly-orthogonal, projections of the received signal, which is assumed to be contaminated with interference, into one or more orthogonal projection spaces based on properties of the signal of interest. Once separated into orthogonal projection space(s), the system and method use information contained in the orthogonal projection space(s) to separate the signal of interest, or target signal, from the interference and to mitigate the interference.

摘要： A method includes receiving, with an antenna-receiver connected to a platform in a group of platforms, a set of uniquely identifiable signals transmitted from respective antennas separate from the platform; defining a first coordinate frame using the location of the antennas; determining, with a platform processor in communication with the at least one antenna-receiver, a position of the platform in the first coordinate frame, the platform processor identifying the position of the platform using one or more characteristics of the uniquely identifiable signals; generating, with the platform processor, a transformation from a coordinate frame defined by the group of platforms to the first coordinate frame; and receiving information at each of the platforms regarding a non-cooperative target. The transformation from a coordinate frame defined by the platforms to the first coordinate frame enables engagement systems and tracking sensors to extend their effective operating range.
