Radar radio frequency (RF) stealth of fighter plane is the important side of stealth fight at fight plane tracking model. First, the RF stealth concept is introduced. Secondly, an optimization control model restricted by tracking precision and accumulation intercept probability is constructed for single target tracking problem. Thirdly, the control strategy of the radar adaptive emission interval and emission power is put forward through solving the model. Finally, by comparison with two other control models FRIAF，FRIFE by computer simulating, the RF stealth ability of the fighter plane is improved .
