摘要： A method and apparatus which perform efficient projection of 4-dimensional data (3 spatial and 1 time dimension) onto planar grids are described. Multiple frames of data are drawn from a limited time history data buffer and projected onto a planar grid, which need not be flat, defined in its own coordinate system. Higher dimensional data structures can also be formed from multiple projection grids. Measurement data from multiple data frames is projected into the planar grid such that distance out of plane is the z-dimension. Computational efficiency is achieved by processing only those data samples that are relevant to the planar grid. To be considered relevant, the impulse response of the sensor's measurement rays must cross the planar grid. Samples of relevant rays must also map onto the planar grid's coordinate mesh to be relevant. Multiple data measurements may determine the planar grid's final amplitude result. Amplitudes at the planar grid coordinates are determined by the most relevant measurement(s) of those within the extent of the measurement system's impulse response.

摘要： A classifier employing general frame wavelets for improving target recognition while decreasing computational intensity is disclosed. A wavelet selection means compares a portion of a time dependent input signal from a receiver with a set of sample wavelets, each wavelet being bandpass limited, locally supported, and mean zero, and selects a prototype wavelet resembling the input portion. A resolving means expands the prototype wavelet onto a basis of wavelet functions having variations in scale and delay, and resolves the input signal onto the basis of functions. A regionpass filter identifies a region from a grid of resolved coefficients that contains features of a target from the input signal and discards coefficients outside the region. A separability filter passes select coefficients from a scale band within the identified region where separability among known targets is high. A comparator compares the selected coefficients with an exemplar of known targets to indicate a recognition of the target.
