多功能X波段雷达探测UAV的非线性信号处理方法

Non-Linear Signal Processing methods for UAV detections from a Multi-function X-band Radar

Mohit Kumar, Keith Kelly

摘要:

本文研究了压缩感知(CS)、主成分分析(PCA)、迭代自适应方法(IAA)和多输入多输出(MIMO)等非线性处理技术在便携式雷达系统增强无人机检测中的应用。该组合方案具有许多优点,并且具有更好的检测和分类精度的潜力。这里讨论的一些好处是考虑到相控阵平台,敏捷射频系统(ARS)的新型便携式相控阵雷达(PWR),它提供象限输出。由于目标多普勒频率的稀疏性,CS和IAA在应用于雷达回波的微多普勒处理时都显示出有希望的结果。这显示出减少停留时间和增加可以询问体积的速率的前景。随着基于GPU的图形处理硬件的出现,利用迭代和非线性解决方案对目标信息进行实时处理现在是可能的。模拟结果显示了良好的效果。

英文摘要:

This article develops the applicability of non-linear processing techniques such as Compressed Sensing (CS), Principal Component Analysis (PCA), Iterative Adaptive Approach (IAA) and Multiple-input-multiple-output (MIMO) for the purpose of enhanced UAV detections using portable radar systems. The combined scheme has many advantages and the potential for better detection and classification accuracy. Some of the benefits are discussed here with a phased array platform in mind, the novel portable phased array Radar (PWR) by Agile RF Systems (ARS), which offers quadrant outputs. CS and IAA both show promising results when applied to micro-Doppler processing of radar returns owing to the sparse nature of the target Doppler frequencies. This shows promise in reducing the dwell time and increase the rate at which a volume can be interrogated. Real-time processing of target information with iterative and non-linear solutions is possible now with the advent of GPU-based graphics processing hardware. Simulations show promising results.
