In this paper, we address the problem of range-Doppler map evaluation in continuous wave radar exploiting OFDM signals. This stage is usually implemented by resorting to a suboptimal batches algorithm and typical choice fragment signal with length equal symbol apply at each batch an appropriate range compression strategy: typically, either Matched Filter (MF) or Reciprocal (RF). The former prov...

Abstract In this paper, we propose a signal processing method in passive radar using the multi-user (MU) multiple-input multiple-output (MIMO) orthogonal frequency division multiplexing (OFDM) as illuminator of opportunity. The MU-MIMO-OFDM modulation is adopted fifth-generation (5G) communication. We consider scenario where multiple mobile users share same time–frequency resources but separate...

Compressive sensing (CS) provides a new paradigm in data acquisition and signal processing for radar. In this work, we investigate the performance of several deterministic waveforms for the basic problem of range-only estimation in CS-radar system. We investigate the effects of a digital RF system from signal generation at the transmitter, to sparse signal recovery at the receiver, on the incoh...

Advances in information technologies are narrowing the gap that traditionally existed between computing methods for radar signal processing, digital communications, and digital signal processing in general. A new field is becoming more stable as new applications and challenges are met for on board, real time operations. This field is termed computing methods for radar communications signal proc...

The presence of sea clutter in marine radar signals is sometimes not desired. So, efficient radar signal processing techniques are needed to reduce it. In this way, nonlinear signal processing techniques based on neural networks (NNs) are used in the proposed clutter reduction system. The developed experiments show promising results characterized by different subjective (visual analysis of the ...
