SPECTRAL IMAGERY COLLECTION EXPERIMENT

摘要

The Spectral and Polarimetric Imagery Collection Experiment (SPICE) is a collaborative effort between the US ArmyARDEC and ARL for the collection of mid-wave and long-wave infrared imagery using hyperspectral, polarimetric, andbroadband sensors.The objective of the program is to collect a comprehensive database of the different modalities over the course of 1 to 2years to capture sensor performance over a wide variety of adverse weather conditions, diurnal, and seasonal changesinherent to Picatinny's northern New Jersey location. Using the Precision Armament Laboratory (PAL) tower at Picatinny Arsenal, the sensors will autonomously collect thedesired data around the clock at different ranges where surrogate 2S3 Self-Propelled Howitzer targets are positioned atdifferent viewing perspectives at 549 and 1280m from the sensor location. The collected database will allow for: 1)Understand of signature variability under the different weather conditions; 2) Development of robust algorithms; 3)Development of new sensors; 4) Evaluation of hyperspectral and polarimetric technologies; and 5) Evaluation of fusingthe different sensor modalities.In this paper, we will present the SPICE data collection objectives, the ongoing effort, the sensors that are currentlydeployed, and how this work will assist researches on the development and evaluation of sensors, algorithms, and fusionapplications.
