A customer asks that a multiple PRF radar be designed to have a maximum unambiguous range of 100 km. To maintain a high average power, an unambiguous range of 20 km is selected for the first PRF PRF1. Choose a second PRF PRF2for this multiple PRF radar that will satisfy the 100 km unambiguous range.
What is the unambiguous range for the second PRF?
What is PRF1 and PRF2?
Note there are many possible solutions to this problem. Please do not use the trivial solution in which the unambiguous range for PRF2 is 100 km.
