By using a new numerical code for deriving the spectral energy distributions of galaxies, we have investigated the time evolution of morphological properties, the star formation rate, and the submillimeter flux at 850 µm in high-redshift (z) dusty starburst mergers with mass ratio (m2) of two disks ranging from 0.1 (minor merger) to 1.0 (major one). We found that the maximum star-formation rate, the degree of dust extinction, and the 850 µm flux are larger for mergers with larger m2. The 850 µm flux from mergers at 1.5 ≤ z ≤ 3.0 in the observer frame is found to be a few mJy for major merger cases, and at most ∼ 100 µJy for minor ones. This result suggests that only high-redshift major mergers are now detected by SCUBA with the current 850 µm detection limit of a few mJy. These results imply that LMSA with the expected detection limit of the order of 10 µJy at 850 µm can be used to study high-redshift mergers with variously different m2, and thus provide an important clue to the formation of galaxies in a high-redshift universe.
