为了研究水下未爆弹药应用中基于目标声响应的识别和分类能力，进行了一系列单基地和双基地声散射测量。测量于2010年3月进行，被称为2010年池塘实验（PondEx10），其中淡水池塘含有沙沉积物。测量利用了一个带有移动塔和固定声纳塔的轨道系统。每个塔都装有接收器，而信号源位于移动塔上。对于PondEx10，在移动塔系统的两个不同地面范围内部署了11个目标。声学数据首先使用合成孔径声呐（SAS）技术进行处理，然后对数据进行进一步处理，生成目标强度作为频率和向角函数的声学模板。介绍了从骄傲目标收集的数据处理的初步结果。还介绍了与一种处理技术相关的结果，该技术允许隔离与其他目标非常接近的单个目标的反应。
A series of monostatic and bistatic acoustic scattering measurements were conducted to investigate discrimination and classification capabilities based on the acoustic response of targets for underwater unexploded ordnance (UXO) applications. The measurements were performed during March 2010 and are referred to as the Pond Experiment 2010 (PondEx10), where the fresh water pond contained a sand sediment. The measurements utilized a rail system with a mobile tower and a stationary sonar tower. Each tower is instrumented with receivers while the sources are located on the mobile tower. For PondEx10, eleven targets were deployed at two distinct ground ranges from the mobile tower system. Acoustic data were initially processed using synthetic aperture sonar (SAS) techniques, and the data were further processed to generate acoustic templates for the target strength as a function of frequency and aspect angle. Preliminary results of the processing of data collected from proud targets are presented. Also presented are the results associated with a processing technique that permits isolation of the response of an individual target, which is in close proximity to other targets.
