PULSED RADAR TARGET RECOGNITION BASED ON MICRO-DOPPLER SIGNATURES USING WAVELET ANALYSIS
Radar based automatic target recognition systems are commonly used in perimeter protection and surveillance applications. These systems determine the nature of a target moving in the radar's field of view using its echo signal. Such an echo signal contains the target's micro-Doppler (μ-D) signature …

Investigation of ship target recognition using neural networks in conjunction with the Fourier Mellin transform
… Modified Direct Mellin Transform (FMDMT) for the recognition of ship targets. The FMDMT is a modification of the Direct Mellin Transform for digital implementations, and is applied to the magnitudes of the Discrete Fourier Transforms (DFT) of range profiles of ships. Necessity for the use of the …

Building a Consistent Neuronetwork: Defining Molecular Cues Involved in the Synaptic Target Recognition of Drosophila Melanogaster
"Every synaptogenesis begins with ""synaptic target recognition"", a cell-cell recognition event in which a neuron and its target stably adhere. Herein I describe two transmembrane molecules present on a subset of muscles in the Drosophila embryonic neuromuscular system, Fas3 and Toll, that affect …
