Abstract :
The paper deals with the signal analysis problem encountered with ground penetrating radar (GPR) applications that use the fast Fourier transform (FFT). A technique for improved signal analysis based on superimposing multiple FFT analyses from the same data is presented. Results from applying the technique are seen to reduce the side lobes with minimal increase in main lobe width.
