Abstract:
In this paper, as an active sensor imaging technique, a new target density function in form of the range density function(RDF) is developed by Gabor transform which is called short time Fourier transform (STFT). It is shown that Gabor theory, (STFI) can be used as approach to imaging by active sensors by transmitting a waveform. which is a kernel for this transform. Then an alternative signal dimension reduction approach is proposed to the developed technique by taking advantage of Walsh functions.
