基于不同作用体制下的非扫描激光成像雷达探测技术

Scannerless imaging lidar detection techniques based on different systems

激光成像雷达是激光技术和雷达技术相结合的产物,在军事上有着广泛的应用前景。非扫描激光成像雷达是近年来出现的新型雷达,因没有机械扫描装置,具有高帧频率、宽视场、高可靠性的特点。本文对基于相位法的非扫描激光成像雷达、基于多狭缝条纹管的非扫描激光成像雷达、基于阵列的非扫描激光成像雷达的原理、特点进行了分析,指出了每种体制的局限性,为应用具体背景下的非扫描激光成像雷达体制的选择提供了一定的参考价值。

With the development of the laser and radar technology,imaging lidar has been widely used in the fields of military applications.Without the scanner devices,scannerless imaging lidars have the characteristic of high frame rate,wide field of view and high reliability.Three kinds of scannerless imaging lidar system,such as based on the phase scannerless imaging lidar,based on the multiple-slit streak tube imaging lidar and based on the flash lidar have been analyzed in this paper.Moreover,the principle,the characteristics and limitations are investigated.Valuable conclusions are proposed for the selection of scannerless imaging lidar in certain circumstance.
