Problems

1. Compute the minimum range for a radar using pulse lengths of 1 ns, 1 μs,
and 1 ms.

2. A radar transmits a series of 10 μs long pulses at a PRI of 100 μs.
Determine the maximum and minimum target range such that at least a
portion of the echo from one pulse will arrive back at the receiver during
the transmission of the next pulse. Targets in this range interval will be
completely or partially eclipsed. What target range produces a completely
eclipsed echo?

3. Suppose a radar has a pulse length of 100 ns. What is the Rayleigh
