radarPower {sonicscrewdriver}

The radar equation

Description

Calculates the power returned from an echolocation pulse

Usage

radarPower(P_t, r, area, G_t = 1, G_r = 1, wl = 1)

Arguments

P_t

Power transmitted (from sender)

r

Range of the target

area

Effective cross-sectional area of the target

G_t

Transmitter gain

G_r

Receiver gain

wl

Wavelength (use only with G_r and G_t)

Value

The received power

Examples

radarPower(12, 20, 0.05)
radarPower(12, 20, 0.05, G_t=1.2, G_r=1.5, wl=0.045)
