You may use IR sensor for the detection of object under water. ultrasonic sensor may also be used also to measure and detect the distance and presence of object

Target moving? With what speed?

What distance?

Target is what? metal, or some fish?

What is visibility of water?

Infra-red is severely attenuated in water so probably isn't a good choice. Ultrasound would be the obvious method to consider.
