In this thesis, we study the new imaging theory developed that incorporates target motion during data collection for the imaging process. The subject of radar imaging from scattered waves is explored and incorporated into the new imaging approach. A simulation model using MATLAB is developed to simulate the imaging algorithm and also to validate the performance. It is shown that the new imaging...

Paper presents description of the principle of work, structure and basic technical parameters of the Maritime Coastal Surveillance Frequency Modulated Continuous Wave (FMCW) Radar CRM-203 type constructed by Telecommunication Research Institute Ltd. in Gdańsk. Results of its tests in real conditions and comparison with pulse ship radars with scanners installed in the same place will be presente...

The paper presents a novel approach, based on the wavelet decomposition and the learning vector quantisation algorithm, to automatic classification of signals with linear frequency modulation, generated by radar emitters. The goal of radar transmitter classification is to determine the particular transmitter, from which a signal originated, using only the just received waveform. To categorise a...

Abstract—The design of a differential K-band UWB (Ultra Wideband) Short Range Radar (SRR) transmitter in 90 nm bulk CMOS is presented. Implementation of SRRs in deep submicron CMOS technology is attractive, in terms of cost and monolithic integration of RF font-end with signal baseband processor. The transmitted pulse bandwidth limits the range resolution of the radar system. Due to the wide ba...

Passive radar systems exploit non-cooperative transmitter to detect targets in areas of interest. Some of the main advantages of such systems with respect to conventional radars include low cost architectures, low energy requirements and potentially null probability of intercept. Digital waveforms like DVB-T and UMTS signals offer relatively wide bandwidth channels which allow achieving good sp...

The design of an integrated rectangular microstrip patch array antenna with enhanced isolation characteristic between transmitter and receiver is presented to produce a full-duplex transceiver with transmit and receive operation at the same frequency and with the same polarization. This integrated circulator-like antenna has potential uses in both short-range communication systems and radar.

In the traditional transmitting beamforming radar system, the transmitting antennas send coherent waveforms which form a highly focused beam. In the multiple-input multipleoutput (MIMO) radar system, the transmitter sends noncoherent (possibly orthogonal) broad (possibly omnidirectional) waveforms. These waveforms can be extracted at the receiver by a matched filterbank. The extracted signals c...

Cognitive radar is a new paradigm to conceive the next radar generation characterized by unique and amazing features inspired to mental abilities and processes related to knowledge. Introduced by Haykin [1] and Guerci [2], it is attracting huge attention within the radar community during the last few years. The key concept is that radar system performance can be enhanced through a continuous an...

The separation of transmitter and receiver in bistatic and multistatic radar sensors offers the system designer new and additional degrees of freedom to tailor solutions to specific applications. The receivers may be passive and hence largely immune to jamming. Passive systems that also use ‘illuminators of opportunity’ do not have to provide a potentially expensive transmitter. Multiple transm...
