Abstract
A neural network radar processor ( ) comprises a multilayer perceptron neural network ( ) comprising an input layer ( ), a second layer ( ), and at least a third layer ( ), wherein each layer has a plurality of nodes ( ), and respective subsets of nodes ( ) of the second ( ) and third ( ) layers are interconnected so as to form mutually exclusive subnetworks ( ). In-phase and quadrature phase time series from a sampled down-converted FMCW radar signal ( ) are applied to the input layer, and the neural network ( ) is trained so that the nodes of the output layer ( ) are responsive to targets in corresponding range cells, and different subnetworks ( ) are responsive to respectively different non-overlapping sets of target ranges. The neural network is trained with signals that are germane to an FMCW radar, including a wide range of target scenarios as well as leakage signals, DC bias signals, and background clutter signals.
