| Abstract: | This paper has analysed the nonlinearity of the varactorFM oscilator in the FM ranging system and its influence on rangingprecision. A specific correction method is put forward. Besides, theprinciple, the circuit and the CAD program of correction are describedin detail. Through nonlinear correction we has notably raised theranging precision. |
