<p><P>PROBLEM TO BE SOLVED: To automatically shape pulse waveform that has been manually adjusted. <P>SOLUTION: A pulse signal having a Gauss waveform generated by a waveform generation part 14 is subjected to modulation processing by a waveform transmission part 15 to be converted into a transmission frequency, power-amplified by a high-frequency amplifying part 16, and transmitted from an antenna used in common for transmission and reception via a coupler 17 or the like. The signal, branched by the coupler 17, is transmitted to an error quantity evaluation part 18, and its input pulse signal is compared with an ideal waveform, and it is evaluated whether an error quantity between both signals lies within a specified error range, When the quantity lies out of the specified error range, a pulse waveform generated by the waveform generation part 14 is corrected by a waveform pattern determining part 19; correction is controlled properly, corresponding to the evaluation result of the error quantity; and thereby the waveform of an output pulse signal approaches the ideal waveform; and ultimately, a waveform pattern acquiring an output pulse signal within the specified error range is determined. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
