Abstract
Improved non-cooperative radar apparatus locates and type-classifies an agitated, vibrating reflective target (e.g., a vehicle with its engine running) - whether the target is moving or stationary. A receiver with a cooperating band pass filter extracts a reflected, frequency-shifted energy pattern from a frequency limited band exceeding the Doppler-shifted emitted interrogation wave to identify the incidence of the agitated target. In accordance with further aspects of the instant invention, the particular energy distribution for the returned, reflected wave is then compared with a stored ensemble of such distributions, or target "signatures", to type-catagorize the target.
