This paper examines the principles of operation of the ballistic detector in the presence of thermal fluctuations. We demonstrate the importance of considering the relativistic aspect when calculating both the dynamics of interaction of fluxons with current heterogeneity and the effect of fluctuations on this dynamics. We present the optimization of parameters of the detector (the value of the bias current and damping, geometrical parameters) in order to maximize the signal to noise ratio.
