Theory & Equations

Radar Range Equation:
\( R = \left(\frac{P_t G_t G_r \lambda^2 \sigma}{(4\pi)^3 S_{min} L}\right)^{1/4} \)

Noise:
\( N = kTB F \)

Range Resolution:
\( \Delta R = c \tau / 2 = c / (2B) \)

Doppler Shift:
\( f_d = \frac{2v}{\lambda} \)

Pulse Radar Ambiguous Range:
\( R_{ua} = \frac{c}{2 \cdot PRF} \)

FMCW Range Resolution:
\( \Delta R = \frac{c}{2B} \)
