A method for demodulating an RF signal to polar in-phase and quadrature (IQ) components that includes converting an RF signal with an analog-to-digital converter and calculating the polar in-phase and quadrature (IQ) components of the RF signal as an IQ phasor phase angle and an IQ amplitude using a digital processor. The analog-to-digital converter uses a sampling rate, where, when the sampling rate used has sampling rates other than 3 times an RF carrier frequency of the RF signal, a digital logic circuit splines data to the sampling rate of 3 times the RF carrier frequency of the RF signal. The digital processor calculates the polar in-phase and quadrature (IQ) components of the RF signal as an IQ phasor phase angle and an IQ amplitude using addition, subtraction, multiplication, division, and absolute value.

A chirped radio frequency signal is transmitted across an area of a potential threat. A reflected radio frequency return signal from an open barrel of a weapon at a location within the area of the potential threat is received at an incident angle through an aperture. An antenna at a position in an antenna array detects the reflected radio frequency return signal received at the incident angle through the aperture. The position of the antenna within the antenna array corresponds to a direction from which the reflected radio frequency return signal originates.
