APPARATUS FOR CHECKING TRANSMITTED WAVEFORM, IN WHICH CONVOLUTION OF TRANSMITTED WAVEFORM AND TIME DELAYED-TRANSMITTED WAVEFORM

摘要

PURPOSE: An apparatus for checking a transmitted waveform is provided to measure a degree of nonlinear distortion of the transmitted waveform by using a correlation method. CONSTITUTION: A waveform delay unit(120) delays a synthesized waveform of a waveform generator during a predetermined period. A correlation signal detector(130) is used for changing the synthesized waveform of the waveform generator according an operation mode and synthesizing the changed waveform with the delayed waveform of the waveform delay unit. A transmitted pulse width detector(140) is used for detecting the transmitted pulse width by checking power of a radar transmitter. A linearity monitor(150) is used for measuring a correlation signal period within the transmitted pulse width, checking the linearity by comparing the correlation signal period with a correlation signal period within another transmitted pulse width, and outputting the checked signal to a radar controller.
