During the mission of developing a remote sensor

the selection of waveband is one of the most important factors for sounding and identifying a target. Aiming at the application like detecting marine target from large area background

major factors which will restrict target detecting were analyzed. As an instance

in case of abyssalpelagic ship target

the SNR and contrasts between target and background at different wavebands within visible/near infrared region were calculated by using atmospheric radiative transfer code—MODTRAN 4.0

and whereupon it was concluded that for wide waveband remote sensor aiming at marine target detecting

the best waveband is from 0.5m to 0.9m..
