C.4 Pattern 4 Multiple reflector respond, figure C.4. At any probe position the A-scan shows a cluster of signal which may or may not be well resolved in range. As the probe is moved the signals rise and fall at random but the signal from each separate reflector element ,if resolved, shows pattern 1 respond.
