Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. A method, comprising: 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 tone waveform from the target; after detecting the object and determining the radial velocity, transmitting, from the LADAR sensor, linear frequency modulation (FM) chirp signals one at a time towards the ta…
