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.
