Abstract
In one aspect, a method includes transmitting a tone waveform from a laser detection and ranging (LADAR) sensor, detecting a target using an echo of the tone waveform reflected from the target, determining a radial velocity of the target using the echo of the monotone waveform from the target, transmitting, from the LADAR sensor, linear frequency modulation (FM) chirp signals and determining a range to target using echoes from the linear FM chirp signals.
