Abstract
Laser radars have the unique capability to give both intensity and full 3-D images of an object or a scene. The latest addition to these capabilities is the possibility to acquire motion. These systems have many civilian and military applications such as terrain modeling, depth sounding, object detection, classification and positioning as well as object tracking. In order to fully understand the performance of laser radars vs experimental data a computer simulation model is of high value. We have developed a modularized computer model capable of modeling performance of a variety of laser radar systems. In order to derive the returned signal waveform from the object one has to account for the laser pulse time characteristics, media effects such as the atmospheric attenuation and scattering as well as object characteristics like shape, BRDF, surface roughness and others. The noise from target speckle and scintillations has to be coupled with detector noise generated by the inherent noise in the detectors and subsequent amplifiers and read out circuitry as well as the noise induced from the optical background. The result can be of help when designing and using new laser radar systems, as well as extending real system parameters and evaluate performance. We will give examples of simulated sensor data in different applications/scenarios together with some real measured data.
