  We report on the measurement of the one-dimensional charged kaon correlation
functions using 600~GeV/{\it c} $\Sigma^-$, $\pi^-$ and 540~GeV/{\it c} $p$
beams from the SELEX~(E781) experiment at the Fermilab Tevatron.
$K^{\pm}K^{\pm}$ correlation functions are studied for three transverse pair
momentum, $k_T$, ranges and parameterized by a Gaussian form. The emission
source radii, $R$, and the correlation strength, $\lambda$, are extracted. The
analysis shows a decrease of the source radii with increasing kaon transverse
pair momentum for all beam types.
