Compared with ambient noise and reverberation has its unique characteristics, one of the most important, the reverberation is caused by the emission signal, and has close relation with the environment, and the waveguide, therefore spectral properties of the reverberation and the target echo
signal under the condition of the Doppler frequency shift is correlation is very strong, and present a strong non-stationarity.
Future work will involve testing UWB radar signal under the complex environment, particularly for very week target echo
detection, and validating the results on the realistic UWB radar scenarios.
In surveillance radars, a single irradiation time towards a target is very short (often 20 to 30 ms), so the target echo
series is a sub-series of the long echo series obtained in the beam-park mode.
The Chameleon ECM simulator is a digital, radio frequency, memory-based, real-lime device that produces jamming techniques and real target echo
stimuli for target radars.
Tenders are invited for X-Band Pxi Based Portable Radar Target Echo
In the novel algorithm, the sparsity of the radar target echo
model is analyzed, and a modified CS (MCS) algorithm is adopted to reconstruct the sparse parameter vectors of target scattering centers along the range distribution.
It is mounted in a compact enclosure and is designed to electronically attack the Lab-Volt Tracking Radar by masking the target echo
signal with noise and cause range or angle deception.
These four complex numbers represent the amplitude and phase (or in-phase and quadrature components) of the received target echo
signal for the specified combination of transmitter and receiver polarizations.
This underwater mobile acoustic aims are torpedo size and simulate the radiated noise and target echo
boost of a submarine and they are utilized to train submarine crews to detect and/or classify targets and for firing training torpedoes as part of on-going weapon and platform acceptance trials for the Royal Navy s submarine fleet, including the latest Astute class.
Furthermore, all these methods mentioned above do not consider the range migration of target echo
during a coherent processing interval (CPI) .
Chapters 5 and 6 deal with target echo
information extraction, including signal extraction from clutter, the threshold setting concept, target velocity measurement and radar height-finding.
