RADAR TARGET IDENTIFICATION USING A COMBINED EARLY-TIME LATE-TIME E-PULSE TECHNIQUE/

The E-pulse technique has been applied in the past to both the early- and the late time components of a transient radar response. While the late-time E-pulse technique uses aspect-independent waveforms, the ear ly-time E-pulse technique requires a separate waveform for each target aspect angle and thus significantly more storage and processing time. This paper discusses a combination of the two techniques that employs the early-time technique to remove ambiguities generated from applica tion of the late-time method. By narrowing the possible range of aspec t angles of the potential targets, the early-time technique can be emp loyed more efficiently.
