Now consider the effect of the staggered PRIs of the previous problem on range coverage.

a. What is the unambiguous range, _{us} , corresponding to the average PRI from Prob. 11? (This would be the unambiguous range of a constant PRI system that used the same amount of time to collect N pulses as the staggered-PRF system.)

b. For the three PRFs in Prob. 11, what is the maximum unambiguous range _{uas}?

c. What is the factor by which the range coverage (unambiguous range) is reduced in the staggered PRF system of Prob. 11 relative to the unstaggered system?

Problem 11

Consider a pulse-to-pulse staggered PRF system using a series of P = 3 PRIs, namely

a. What are the base interval g and the set of staggers {kp}?

b. What is the average PRI, _{avg}?

c. What is the first blind Doppler frequency, _{bs} , of the staggered system?

d. What is the ratio _{bs }/_{b }of the first blind Doppler of the staggered system to the first blind speed of a constant-PRF system having the average PRI _{avg}?
