A novel processor for the generation of a digital terrain model (DTM) using ground-based synthetic aperture radar (GB-SAR) imagery is presented. The performance of the processor has been assessed using the archive of C-band GB-SAR images available at

The problem of the formation of subsurface images using stand-off forward looking radar is by far more severe than that of forming the radar images in the free-space. A subsurface image needs to be accurately focused taking into account both the refr

In this paper the issue of phase discontinuity in MIMO radar systems is analyzed and described in detail, together with an efficient way for processing MIMO radar data by means of FFT. In particular, it is here shown that the phase of a point target

In this paper we investigate the application of frequency and space diversity as means for providing a better understanding of the features of a target. For this purpose space diversity is exploited for developing a way for processing the information

In this paper we extend the investigation on the use of Doppler signatures for human motion detection. As it is well known, human movements generate additional Doppler frequencies on top of the main Doppler carrier. In recent times research has been

In this paper the use of Doppler signatures for human motion detection is presented. This can be of interest during search and rescue missions where visibility can be poor or even absent. Human movements give rise to specific Doppler frequencies. The
