Clutter Reduction and Object Detection in Surface Penetrating Radar
This paper addresses the problem of detecting buried objects using a surface penetrating impulse radar. A big problem is that reeections from the ground surface will obscure the often much weaker target signal. The ground reeections and the target signal are mod-eled using a very simple model. This model is used to derive a detector based on a Likelihood Ratio Test, where unknown model paramete...

متن کاملFusion of Distributions for Radar Clutter Modeling
To recognize an object in an image, an algorithm must identify not only the object pixels, but also non-object clutter pixels. Non-object pixels can be assessed with a priori clutter models that account for the varying terrain and cultural objects. Radar clutter models have been well developed; however, these models typically incorporate a single distribution to capture background effects. In t...
متن کاملRadar Signal Detection in K-distributed Clutter by Pade Approximation
In this paper, two suboptimum detectors are proposed for coherent radar signal detection in K-distributed clutter. Assuming certain values for several initial moments of clutter amplitude, the characteristic function of the clutter amplitude is approximated by a limited series. Using the Pade approximation, it is then converted to a rational fraction. Thus, the pdf of the clutter amplitude is o...
متن کاملThree-dimensional FDTD modeling of a ground-penetrating radar
The finite-difference time-domain (FDTD) method is used to simulate three-dimensional (3-D) geometries of realistic ground-penetrating radar (GPR) scenarios. The radar unit is modeled with two transmitters and a receiver in order to cancel the direct signals emitted by the two transmitters at the receiver. The transmitting and receiving antennas are allowed to have arbitrary polarizations. Sing...
