It's a distinct possibility. RAs use a system of frequency modulated continuous wave radar. A CW signal is ramped up in frequency and the reflected return signal differs in frequency based upon the travel time. So the system isn't range gated, where subsequent pulses can be spread out to avoid such misinterpretation. The failure modes would be something that a radar expert (which I am not) could expand upon.
