Ground penetrating radar (GPR) is a non-destructive geophysical method that uses electromagnetic waves to image the subsurface. A typical GPR system has three main components: transmitter and receiver, directly connected to the transmitting and receiving antennas, and a control unit. Electromagnetic pulses are transmitted into the subsurface and the earth response is recorded. The GPR method is...

R and sonar applications are signalprocessing intensive and heavily rely on the efficient implementation of such digital signal-processing (DSP) algorithms as filtering, transforms and modulation. In past systems, conventional digital signal processors were used to perform many of these algorithms. However, field-programmable gate arrays (FPGAs) deliver an order of magnitude higher performance ...

Radar Signal Processing algorithms place strong real-time performance demands on computer architectures. These algorithms do however have an inherent data-parallelism that allows for great performance on massively parallel architectures, such as the Graphics Processing Unit (GPUs). Recently, using GPUs for other than graphics processing has become a possibility through the CUDA and OpenCL (Open...

Synthetic Aperture Radar (SAR) currently has problems in the processing that lead to smearing of the image. We have developed a new method of processing the data using maximum likelihood theory that will remove the smearing leading to superior images. The goal of this project was to write a MATLAB program to simulate a SAR system to test the new processing method.

Radar is considered an important technology for health monitoring and fall detection in elderly assisted living due to a number of attributes not shared by other sensing modalities. In this paper, we describe the signal processing algorithms and techniques involved in elderly fall detection using radar. Radar signal returns from humans differ in their Doppler characteristics depending on the na...

One fundamental issue in designing a good radar system is it’s capability to resolve two small targets that are located at long range with very small separation between them. Pulse compression techniques are used in radar systems to avail the benefits of large range detection capability of long duration pulse and high range resolution capability of short duration pulse. In these techniques a lo...
