First Claim
Patent Images
1. A system comprising:
- a stepped-frequency radar configured to induce vibrations in a buried object using different frequencies; and
a receiver configured to;
collect, over time at a packet rate, measurement packets from electromagnetic signals associated with the vibrations, and process the collected measurement packets to determine vibration displacement to detect the buried object.

Abstract
A frequency-stepped radar may be used to detect buried landmines by sequentially inducing vibrations of different frequencies in the landmine. A sensor detects signals associated with the vibrations, and a processor processes the signals to detect the landmine.
