We present a modified bootstrap filter (MBF) to draw particles in the particle filter (PF). The proposal distribution for each particle involves sampling from the state-space model a number of times, and then selecting the sample with the highest measurement likelihood. Numerical examples show that this filter outperforms the bootstrap filter (BF) with the same computational complexity when the state noise has a large variance.
