The circuit-level simulation of continuous Wave Doppler Fuze detector based on ADS

Simulation of fuze detector using conventional simulation softwares requires tremendous complicated theoretical calculations. It also can´t analyze the impact caused by the nonlinear of the analog devices. A circuit-level simulation method is proposed in this paper to solve this problem, based on the implementation of continuous wave Doppler fuze detector on ADS simulation platform. Continuous Wave Doppler Fuze detector model is built on the ADS platform by using components and Microstrip Line as the same as real circuit and optimizing the analog components parameters by impedance matching. This model launches a Continuous wave signal which has the frequency between 3.36GHz and 3.5GHz, and generates an IF signal of a magnitude between 150mv to 200mv. The results show that this scheme is reasonable and feasible.
