Abstract: A system and method for mitigating Analog to Digital (A/D) clipping is disclosed. The mean and variance of analog input data are tracked and the bits of A/D are dynamically reassigned to keep the input signal within their range. The quantization levels of A/D are dynamically re-mapped to avoid changes in sensitivity of sensor system. The method is based on random walk statistic and keeps the sensitivity of the sensor system constant. Also the system and method provides a way to mitigate A/D clipping that avoids changing the sensitivity by dynamically re-mapping the quantization levels of the A/D, keeping the sensitivity of the system constant.

Abstract: A system includes a way of improving an image obscured by airborne particles. The system includes a decomposition processor and an image generation processor. The decomposition processor decomposes an object of interest moving in a first image at a first rate of speed into at least one first subspace vector. This decomposition processor also decomposes fine particles moving at a different rate of speed than the object in the first image into at least one second subspace vector. The fine particles obscure the object of interest in a second image. The image generation processor generates based, at least in part on the first subspace vector and the second subspace vector, an image of the object without some of the fine particles obscuring the object of interest.

Abstract: A system and method for detecting the trajectory of a projectile is presented. One system includes a flash detection sensor, an acoustic sensor, an optical sensor and a processor logic mounted on a vehicle. The flash detection sensor detects a flash of a projectile being launched. The acoustic sensor detects when a blast wave associated with the firing of the projectile reaches the vehicle. The optical sensor takes two or more images of the same projectile. The images are typically not in the visible light spectrum. The processor logic calculates a trajectory of the projectile based on the images and data collected by the acoustic sensor associated with the blast wave. The processor logic may generate a warning signal to warn an operator of the vehicle about the projectile.
