摘要

为步进频率探地雷达(SFGPR)应用设计并测试了一种工作频率在600 ~ 3000 MHz范围内的宽带双臂槽形螺旋天线。这种天线是低轮廓，平面，使用一个简单的电流元件作为平衡馈电。以埋在干砂中的金属棒为研究对象，研究了SFGPR模式下接收机中频(IF)带宽(BW)对天线信噪比的影响。

Design and validation of slot spiral antenna for stepped frequency ground penetrating radar

A wide band dual arm slot spiral antenna operating over 600 MHz to 3000 MHz was designed and tested for a Stepped Frequency Ground Penetrating Radar (SFGPR) application. This antenna is low profile, planar, uses a simple current element as the balanced feed. The influence of the receiver Intermediate Frequency (IF) Band Width (BW) on the Signal to Noise Ratio (SNR) for antenna operation under SFGPR mode is investigated for a metal rod buried inside dry sand.
