Convert propagation distance to propagation time
t = range2time(r)
t = range2time(r,c)
Calculate the required PRF in Hertz for a monostatic radar system so that it can have a maximum unambiguous range of 15 km.
r = 15.0e3; prf = 1/range2time(r)
prf = 9.9931e+03
r— Signal range
Signal range in meters, specified as an array of nonnegative numbers.
c— Signal propagation speed
Signal propagation speed, specified as a positive scalar in meters per second.
