Considering the effect of initial value on the output state of chaotic oscillator based weak signal detection system, this paper has done an in-depth analysis on the global behavior nearby bifurcation point with generalized cell mapping method. According to the simulated numerical analysis results, a method for detection system without false positive rate is proposed. Response step is defined as the index to measure the detection speed, with which the speed of detection system responding weak signal has been analyzed. The conclusion provides support for implementation of chaotic oscillator detection system.
