Automatic radar target identiication is a very diicult task because data are very noisy and very few is known to decide which part of the signal is important. Iden-tiication techniques could help to build more eecient radars but also to better understand how this signal could be interpreted. We present here some connectionist techniques that have been tested on this task. They ooer rather good ...

Radar cross section (RCS) sequences, an easy-to-obtain target feature with small data volume, play a significant role in radar classification. However, classification based on RCS sequences has the shortcomings of limited information and low recognition accuracy. In order to overcome RCS-based methods, this paper proposes spatial micro-motion method encoding convolutional neural network (CNN). ...

this paper addresses the signal processing principles in passive bistatic radar (pbr) systems. in this case, the detection problem in the presence of system noise, clutter/multipath, direct signal and interfering target signals is investigated. to this light, two types of detectors are studied. in the first one, which is based on intuitive sense, we examine two detectors. in the second type det...

This paper presents a method of imaging a twodimensional section of a walking person using multiple Doppler radar systems. Although each simple radar system consists of only two receivers, different radial speeds allow target positions to be separated and located. The signal received using each antenna is processed employing time–frequency analysis, which separates targets in the time–range– ve...

This paper presents a method of imaging a two-dimensional section of a walking person using multiple ultra-wideband Doppler radar systems. By exploiting multipath echoes, we can increase the effective number of radar systems virtually. Although each simple radar system consists of only two receivers, different line-of-sight velocities allow target positions to be separated and located. The data...

Scientists have explored that WiMAX has the potential to enhance the performance of the radar networks. With the idea of implementing MIMO (multi-input multi-output) communication technology for overcoming the challenges offered by hostile channel and environmental effects.It leads the technocrats to utilize this technology in radar operations. WiMAX MIMO can exploit the range of WiMAX and the ...

This paper presents a method of imaging a twodimensional section of a walking person using multiple ultrawideband Doppler radar systems. Although each simple radar system consists of only two receivers, different line-of-sight velocities allow target positions to be separated and located. The signal received using each antenna is processed employing time– frequency analysis, which separates tar...

The basic concept of radar is relatively simple even though in many instances its practical implementation is not. A radar operates by radiating electromagnetic energy and detecting the echo returned from reflecting objects (targets). The nature of the echo signal provides information about the target. The range, or distance , to the target is found from the time it takes for the radiated energ...
