Can anyone help me with a Ultrasonic Radar with can be worked in unison with my Computer to detect any movement.

These guys make a some kits for robotics
This device is an ultra sound range detector, to make a real radar you would also want to add a motor to rotate it and some way of measuring where it was pointing.
