Question #158561

Two point targets are separated by 3m in slant range, (a) What radar bandwidth is required to resolve the two targets? (b) If the radar is a monotone pulse radar, what should be the maximum transmitted pulse duration?

Expert's answer

Distance between the targets = 3 m

a)

The radar Range Resolution (d) is given by;

"d=\\frac{c}{2B}"

"\\frac{3 \\times10^8}{ 3\\times B}= 3"

"B = 5 \\times10^7 Hz = 50MHz"

b) The pulse duration of radar pulse is given by:

"\\tau =\\frac{1}{B}"

"\\frac{1}{(5\\times 10^7)} = 0.2\\times 10^7 s"
