The change of the gyroscope s resonant characteristics under different air pressure was studied and the experiment on the frequency matching of the drive axis and sense axis was carried out.

A frequency matching method for stochastic resonance control is presented on the assumption that stochastic synchronization of stochastic resonance will be generated when the nonlinear bistable system is stimulated by noise and weak periodic signal.

The paper advices a whole resolve scheme of triangle wave modulation automotive anti-collision radar which has two channal receivers, gives interfere wave eliminate means and frequency pairing up means, including their signal processing means and their flow charts when the radar measures ranges and relative speeds of multi-objects.
