Hi Ananya,
Based on the information provided, duplicates occurred when the same target is detected by multiple radar pulses. This can happen if the radar pulse repetition frequency (PRF) is too low, which means that the time between consecutive pulses is long enough for the target to move to a different location. When a subsequent pulse is transmitted and received, it may detect the same target at its new location, creating a duplicate in the radar data.
Another scenario where duplicates can occur is when multiple radars (for example, the MIMO case itself) are used to detect the same target. In this case, each radar may detect the same target independently, creating duplicates in the radar data.
with regards,
