Title: Radio wave classifying device
Inventor: ASA TOMIO
IPC: G01S7/292
Filed: 1995-10-18
Abstract: PROBLEM TO BE SOLVED: To more accurately classify pulse signals from a plurality of radio wave radiating sources. SOLUTION: A radio wave classifying device classifies radio waves from a plurality of radio wave radiating sources in accordance with the rate of change of the intensity of a received electric field and outputs the classified radio waves for display. When the classifying device classifies the radio waves, gate width setting circuits 50-1 to 50-N specify a prescribed range with the intensity of the electric field received at the preceding time as the central figure. Pulse amplitude gate circuits 40-1 to 40-N output the received radio waves as the same kind of radio waves as those of the preceding time when the intensity of the received electric field falls within the range or another kind of radio waves when the received electric field intensity does not fall within the range.  Since the radio waves are classified in accordance with the received electric field intensity in addition to the frequency, arriving azimuth, and pulse-repetition frequency of the radio waves, pulse signals can be classified more accurately.
