A neural network discriminator includes a neural network autoencoder and a scorer. The scorer compares an original signal or signature with a reconstructed signal or signature generated in the neural network autoencoder. The scorer generates a similarity score based on the comparison. If the similarity score exceeds a threshold value, then the discriminator determines that the source of the original signal is a positive indicator. In some scenarios, the positive indicator refers to a threat, such as a missile or other enemy object that may cause harm, from an open set of signal signatures that the discriminator has never learned or never been exposed to. The discriminator can also determine clutter signatures from the open set of signature that the discriminator has never been exposed to.

A line-of-sight aimpoint tracking system includes a model projecting module that converts a 3D model of an area of interest into a 2D projected image from a platform viewpoint, incorporating an aimpoint in its vicinity, based on platform position and attitude measurement information. A registering/tracking module aligns this 2D projected image with a real image captured by a video source on the platform, and identifies the aimpoint's pixel location within the real image. After the correlation between the real image and the 3D model has been established based on location information from a GPS, or the like, combined with image registration to perform aimpoint-cueing, interframe registration enables the aimpoint to be tracked based on image information in the absence of location information from the GPS, or the like. A line-of-sight estimator then calculates pointing angles of a line-of-sight vector to the aimpoint and provides them to a navigation system.

A precipitation scanning aperture RADAR system comprises at least one transmitting satellite (TX) and a plurality of receiving satellites (RXs) flying in a multi-static formation. The TX emits fixed frequency, pseudo-random, non-repeating phase modulated RADAR energy. Range and Doppler information is extracted from reflected signals received by the RXs to form coherent 2D along track/vertical images, which are combined into a 3D reflectivity map using a power-based incoherent modeling algorithm, such as a Gaussian mixture model. Embodiments implement a spotlight mode in which, for each RX, a plurality of the coherent 2D images obtained during successive coherent processing intervals (CPIs) are incoherently combined, and the satellites adjust their orientations between each CPI to compensate for satellite movement. Inter-satellite timing synchronization of 10 ns or better is sufficient for forming the 3D reflectivity map. The range and Doppler information can be extracted by concurrently demodulating at a plurality of reference frequencies.
