【Abstract】 A new method is presented which is named Subsection Calibration method of crystal diode radio detector, which utilizes linear regression theory, calibrates the stationary wave range of the measurement system sectionally from the wave node to the wave loop, and gains several different disciplinarian parameters of the crystal diode diode detector. In the process of microwave measurement, CAT (Computer Aided Test) system searchs an appropriate disciplinarian parameter according to the real measuring range, then works out the corresponding result. This new method minimizes the measurement errors aroused by crystal diode radio-detector effectively and enhances the accuracy of microwave measurement.更多还原
