Bernoulli filter for joint detection and tracking of target with low signal to clutter ratio

Abstract

In this paper, Bernoulli filter is directly applied to filter the detection results from the range Doppler plots and showed the ability to track targets at the condition with low signal to clutter ratio (SCR). Using Weibull distribution to simulate clutter and adding the target with different power, we obtain the range Doppler plots with different SCR. And then, the test results of the range Doppler plots are treated as the input of Bernoulli filter. Simulation results show that the Bernoulli filter can track targets properly even in the condition of SCR=10dB, in which the visual cannot distinguish target. Therefore, Bernoulli filter can play an important part in actual target detection and track, especially in small target track.
