The postholder will be required to carry out research on bistatic radar clutter and target
signatures. This work will include designing and running computer simulations, designing
hardware and designing and conducting experiments, and recording, analysing and writing
up the results as part of a research team.
Bistatic radar, where the transmitter and receiver are separated by a significant distance,
comparable with the target range, has a long history. Only in the past decade, though, have
many practical systems started to be developed. One reason that this is only just starting to
happen is that bistatic radars are significantly more complicated than conventional
monostatic systems. Now, however, applications are becoming evident where bistatic
operation offers a genuine advantage, and geolocation and synchronisation is made much
easier by GPS. The present interest in MIMO (Multiple-Input, Multiple-Output) radar, which
is a subset of multistatic radar, is indicative of this.
Part of the development of bistatic radar will be to gain a proper knowledge of the
properties of bistatic clutter and targets. This will be important to give a proper
understanding of detection performance, to be able to optimise detector performance, and
also in the measurement of radar performance for acceptance purposes.
Over recent years University College London (UCL) has developed a unique low cost three-
node S-band (2.4 GHz) multistatic radar system known as NetRAD, which is capable of a wide
range of radar measurements (Figures 1 and 2). The system was used initially in the UK for
gathering data on a range of targets in both cluttered urban environments and low clutter
rural areas. In its initial form the transmit power was relatively low (200 mW peak power at
each node) but this was subsequently upgraded such that one node is now capable of 500 W
peak transmit power, making the system suitable for measurements of longer range and of
distributed targets. As well as this, a set of GPS-disciplined oscillators were developed by the
University of Cape Town (UCT), which have allowed fully coherent operation without the
need for the nodes to be physically interconnected by cable.
The radar has been used to undertake experimental trials in 2010/2011, gathering data on
sea clutter and small maritime targets. Analysis of the clutter data has led to the important
conclusion that the amplitude statistics of bistatic sea clutter may be shorter-tailed than the
equivalent monostatic clutter (Figure 3), and hence that there may be a performance
advantage to the bistatic configuration in detecting small targets against clutter [1, 2] (Figure
4). This affect appears to be a strong function of the bistatic geometry, so in order to best
exploit it, it is necessary to understand the dependence on all the various factors – which I
have termed ‘clutter diversity’. Although the effect has been observed in all of the
experimental data acquired and analysed thus far, it is not clear whether it holds generally,
or only under certain conditions. One of the key aims of the proposed research will be to try
to answer this question.

In order to do this it in a full and proper manner, the existing NetRAD system needs to be
upgraded, to provide multi-band operation (probably L-band and X-band in addition to the
existing S-band), with appropriate transmitter and receiver hardware and automatically-
steered antennas. The new hardware will exploit software-defined radio modules, which
provide a low-cost and low-risk approach.
Figure 3: Fit of compound K-distribution model to Figure 4: The shorter tail of the amplitude
bistatic data from NetRAD shows excellent distribution of the bistatic clutter allows a lower
agreement detection threshold, and hence improved
detection sensitivity for a given probability
of false alarm
Once this is done, trials will be undertaken against a range of land (rural and urban) and sea
clutter backgrounds and targets.
The specific objectives of the study are:
To upgrade the NetRAD radar hardware to provide multi-band operation and
To undertake experimental trials to gather clutter and target data as a function of
bistatic geometry, polarisation, frequency and surface type
To develop models for the clutter (in terms of mean reflectivity, amplitude statistics
and Doppler spectra) and for targets

About UCL and the Department of Electronic and Electrical Engineering
University College London (UCL) was founded in 1826 as the third university in England, after
Oxford and Cambridge. UCL was however the first university in England to admit students of
any race, class or religion, and the first to welcome women on equal terms with men. UCL is
now the largest comprehensive university in London with more than 4,000 academic and
research staff in 72 departments. The main campus of UCL is located in central London, just
a few minutes walking distance from British Museum, West-End and Thames River.
The Department of Electronic and Electrical Engineering at UCL was established by Professor
Sir Ambrose Fleming in 1885 and has a very strong research culture, state-of-the-art
research equipments and facilities, and a very rich history of many fundamental research
achievements in electronic and electrical engineering. The Department currently hosts
international renowned research groups in Communications and Information Systems;
Photonics; Optical Networks; Sensors, Systems and Circuits; Electronic Materials and Devices
and Nanotechnology. For more information about the department and our research
achievements, please visit the website http://www.ee.ucl.ac.uk
