Minimum radar range = (pulse width + *recovery time) × 164 yards*In most modern radar systems, recovery time is negligible and does not need to be considered whenfiguring minimum radar range.Radar range resolution (in yards) = pulse width × 164 yards per microsecond.When you use the term decibel (dB), you are referring to a logarithmic comparison between twosignals, usually the output and the input. In power measurement applications, however, a reference of 0dBm equalling 1 milliwatt is usually used. The term dBm is used to represent power levels above, below,or at 1 milliwatt.The following formulas are used for figuring dB:In circuits where impedances may vary:Some basic information to remember:1-38
