First Claim
Patent Images
1. A detection and classification system utilizing unipolar pulses comprising:
- directional unipolar pulse transmitting means with radiated energy in limited parts of frequency spectrum;
receiving means adapted for receiving target signal returns in broad frequency spectrum resulting from pulses transmitted by said directional unipolar transmitting means; and
readout means coupled to said receiving means.

Abstract
A detection and classification system utilizing a transmitter to generate a successive series of unipolar pulses which are then radiated into propagation space by a directional radiator; a receiving system to detect with an antenna and amplifier the especially distinctive low-frequency returns which are then filtered, processed and recorded in order to reconstruct and thus to classify the signal returns.
