<P>PROBLEM TO BE SOLVED: To easily correct distortions that have occurred in pulses. <P>SOLUTION: A distance measuring device comprises: analog circuits 206, 207, 208 that synthesize interrogation pulses having been received from an aircraft and an ideal waveform of interrogation pulses received from the aircraft to convert into analog signals and to perform a process for detecting the interrogation pulses; an A/D converter 208 for converting the interrogation pulses having been processed in the analog circuits 206, 207, 208 into digital signals; and a correction executing section 212 that utilizes differences between the interrogation pulses having been converted into the digital signals by the A/D converter and the ideal waveform of the interrogation pulses received from the aircraft to generate new interrogation pulses in which distortions having occurred in the interrogation pulses in the analog circuits 206, 207, 208 have been corrected. <P>COPYRIGHT: (C)2012,JPO&INPIT |
