Minimum radar range = (pulse width + *recovery time)
*In most modern radar systems, recovery time is negligible and does not need to be considered when
figuring 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 two
signals, usually the output and the input. In power measurement applications, however, a reference of 0
dBm 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:
