| Abstract: | The hardware and software electrocircuit of radar feed location instrument were designed by using triangular wave modulation. They were switched capacity filter chip based on the principle of linear frequency-modulation continu-ous wave feed location instrument, and the performance of the designed instrument was also tested. The test results indi-cated that this instrument could accurately measure the height of materials in the distance of 2 to 40 m, and the relative error was less than 1%. This system has the character of low price and high accuracy. |
