A radar system uses two ambiguous PRFs to determine range. The specifications of the MPRF waveform are exactly the same as in the last problem. The first PRF has 40 range bins as shown below. Examining the range bins in more detail, range bin 24 shows a hit. The apparent range is 24 * 0.25 km = 6 km.
The second PRF has 41 range bins as shown below. There is a hit in range bin 21 for this PRF. Note the shift is from range bin 24 to range bin 21 for this PRF set.
Both of the hits seen previously are ambiguous hits. Combining the information from the two hits, what is the unambiguous range to the target?
