Abstract
Embodiments are disclosed for a range-gated imager. In some embodiments, a method comprises transmitting, with a multi-tone continuous wave (MTCW) radar, a radar signal comprising a first tone and a second tone, where the first tone and the second tone are separated by a frequency gap; receiving, with the MTCW radar, a return signal from a projectile impinged by the radar signal; detecting, with a measuring apparatus, a zero crossing of a phase difference between the first and second tones; and responsive to detecting the zero crossing, gating or triggering, by the measuring apparatus, an imager to capture an image of the projectile.
