FPGA signal processing for radar / sonar applications
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 ...
متن کاملAmbiguity in radar and sonar
We introduce a new ambiguity function for general parameter estimation problems in curved exponential families. We focus the presentation on passive and active radar and sonar location mechanisms. The new definition is based on the Kullback directed divergence and reflects intrinsic properties of the model. It is independent of any specific algorithms used in the processing of the signals. For ...

متن کاملChirp Scale Processing for Imaging Sonar
Imaging the sea floor using high precision sonar is at the stage where the efficiency and robustness are of concern. Synthetic aperture sonar (SAS) has the appealing property of range and frequency independent spatial resolution. SAS data’s are more challenging to process than the conventional counterparts, because the towfish is more complicated and usually non stationary. Time domain algorith...
متن کاملUXO Detection Techniques Using Sonar and Radar
Several approaches to the detection of Unexploded Ordnance (UXO) in the ground are discussed. Methods exploiting the coupling of sound into the earth are shown to have promise. These approaches can use both linear and non-linear phenomena as clues. Also discussed is the potential of a ground penetrating radar method that is based on a nonlinear phenomenon.
