RADAR STATION WITH PULSE-BY-PULSE CARRIER FREQUENCY TUNING, NEURAL NETWORK RECOGNITION OF OBJECTS AND INVERSE ANTENNA APERTURE SYNTHESIS

摘要

FIELD: physics.;SUBSTANCE: disclosed device includes a storage buffer, an inverse fast Fourier transform unit, a normalisation unit, random access memory, a first neural network classifier, a first digital switch and L second neural classifiers, where L is the number of recognised classes of aerial objects, a unit for generating a redundant data matrix, a correlation analysis unit, a unit for generating a multi-frequency synthesised scattering matrix, an inverse fast Fourier transform unit, a phase distortion compensation unit, a zero extension unit, a direct fast Fourier transform unit, an image forming unit, a feature generating unit, a second digital switch and L third neural network classifiers, each having Z outputs on the number of recognised types of objects within one class, connected in a defined way with each other and the rest of the components of the device.;EFFECT: enabling radar recognition of classes and types of aerial objects within one of the classes at any range to the object.;2 dwg
