Abstract
For a long time the use of different waveforms for radar applications
have been studied. First radars used short pulses, but high peak
power – up to megawatts. The development of signal processing
lead to more advanced waveforms. To decrease the peak power the
concept of continuous wave radar was introduced and nowadays
there are many FMCW radars using linear frequency modulation
and low power. FMCW radars with linear modulation are very
popular, because after the homodyne receiver the signal processing
is based on FFT and it is possible to achieve high range resolution
with low sampling rate and low computational power.
At the computational power is no longer the main limitation in
radar technology, a lot of new ideas and different radar concept is
being investigated. While one of the main disadvantage of classical
radars is range and velocity ambiguity related to repetition of
transmitted waveform, the scientist are looking for non-periodical
waveforms with desired properties. One of such waveforms is
random or pseudo-random signal, similar to white noise.
The first investigations on applying noise signals for radar purpose
are dated from the half of XX century, but the research sped up
in the last decade. A radar using noise waveform is free from
ambiguities, and due to continuous illumination of targets it can
be used both for detection and target imaging using SAR and
ISAR concept. Very low power density of emitted noise signals
contributes to LPI nature of such radars and even if detected are
difficult to identify.
During the workshop the scientists from Italy, Ukraine and Poland
will deliver their new results in this emerging field of knowledge.
The attendees may learn a lot about this new radar technology
and discuss problems with the researchers working currently in the
novel area of radar technology.
The presentation will start with introduction to Noise Radar
Technology with an overview of the basic ideas, problems and
achievements. The second talk will be dedicated to target imaging
using noise radar and will be held by prof. Lukin who started the
Noise Radar Technology conferences in 2002. The third presentation
will go deeply into signal processing describing cross-ambiguity
function modification for target detection, the CLEAN algorithms
to reduce masking effects end sparse sensing to improve the
target imaging for non-cooperative target recognition. The final
presentation will be focused on modern MIMO radars using
noise and noise-like waveform to increase radar sensitivity and
functionality. The presentation will highlight the concept of MIMO
radars, show different waveforms used in such systems and finally
show how to design noise waveforms for MIMO radar.
