A general-purpose remote sensing lidar system model has been developed for use with aerosol targets as well as hard targets in various atmospheric conditions and battlefield aerosol smoke conditions to model the actual analogue return waveform. A description of the model with equations and some of the aerosol parameters are presented. An empirically determined impulse response function from a commercially developed short-range system that operates at 0.905 micrometers is used in the prediction of the analogue output waveform for this particular system. The computed waveforms show the effects of backscatter for aerosol smoke conditions. Some experimental validation of the model for a hard target in military fog oil smoke is shown. This model will be used to predict performance of the current lidar sensor as well as other senors under various other atmospheric and battlefield smoke conditions.
The Low Cost Gun Launched Seeker is a component of the Navy's effort to develop effective weapons for surface fire support missions by enhancing the performance of projectiles like the Extended Range Guided Munitions with low-cost, uncooled infrared (IR) staring focal plane array terminal seekers. IR target images for validating target detection algorithms were collected using a Merlin long wave camera from Indigo Systems. This paper characterizes the camera in order to develop performance parameters for simulating the seeker and to understand features in the imagery. These parameters include temperature response, temporal noise characteristics, fixed pattern noise, and the modulation transfer function.
Temperature dependent infrared transmittance measurements and room temperature BSDF measurements are collected on 1.5mm thick CVD diamond samples produced by De Beers Industrial Diamond Division. The transmittance measurements are from 2 to 20 micrometers covering the temperature range from room temperature to 400 degree(s)C. The BSDF measurements are conducted at wavelengths of 0.6328, 3.39, and 11 micrometers and as a function of the incidence angle. The total integrated scatter is obtained by integrating the BSDF function over all the reflection angles.
