Bistatic Radars

Bistatic Radars are pairs of radar systems where transmitter and receiver are separated and at distant loctions. These bistatic radars play an increasing role, i.e. in military radar technology, when detecting stealth aircrafts. The principle is e.g., applied in semi-active radar applications (long-range air-to-air systems, surface-to-air systems). But bistatic radar systems have more potential than just defence applications.


One of the big challenges in radar technology is to discriminate real targets from clutter. With the advance of technology and IT, more and more refined and powerful solutions are researched and invented. This section aggregates white papers and case studies on recent research results on clutter processing.

Radar Signal Analysis through Data Mining and Mashups

An interesting new direction in research is the opening of radar signal analysis to Cloud-based data aggregation (Mashups) and big data mining. The latter means the connection of different sources of signals, which could be from different sources and/or from different time periods.

Drone Detection

Miniaturisation of UAVs and an increased thread of misuse in EW and terror shifted emphasis on the detection and elimination of drones. Researchers are confronted with the question on how to detect an intruding object into a perimeter, who to identify it, and for e.g., draw conclusions like friend or foe information. This field of research has just emerged and therefore offers news on a weekly basis.

Fast Fourrier Transform FFT

An important algorithm in radar technology is the Fast Fourrier Transform as it allows to split the reflected wave into its constituting waves.

Frequency Modulated Constant Waves Radars FMCW

Frequency Modulated Constant Waves Radars apply the principle of frequency modulation for the detection and analysis of targets. Although it is one of the oldest applied radar principle, this technology continues to be researched for improvements.

Frequency-Shift Keying FSK
Frequency-Shift Keying applies the principle of discrete frequency changes for the detection and analysis of targets. Similar to the way information is stored and read on a CD-ROM, the FSK sequence of a radar signal allows to gain relevant data on a target object through comparing emitted and reflected wave.
GPR Radar Applications for the Detection of Land Mines
Antipersonnel mines and cluster munitions are indiscriminate weapons that injure and kill civilians in every corner of the globe, every day. They don’t recognize ceasefires and claim victims long after the end of conflicts. They instill fear in communities and are a lethal barrier to development. Placed under or on the ground, antipersonnel mines explode from the contact or presence of a person. When triggered, they kill or cause injuries like blindness, burns, destroyed limbs and shrapnel wounds. This section presents applications of ground penetrating radars to detect land mines.
High Resolution Radars
With the increasing diversity of radar applications such as weather radars, interferometry or space observation, the resolution of the radar image continues gaining importance. In this section, we present a sequence of research papers and case studies that focus on the resolution matter.
Linked Open Data in Air Traffic Management
Linked open data is a challenging vision for Air Traffic Management. ATM requires meantimes between failure of more than 10,000 hours. Do we really want to rely on external sources, where the origin is perhaps unknown to us? How save can this be? Can we imagine that air traffic control is opening up to anybody? How far is our mind willing to go? This section is a playground of early research. So we limit it to academic publications and some selected announcements on research and standardization agendas.
Maximum Likelyhood Method for Radar Signal Processing
With computer technology, replacing the traditional Transistor-Logic (TTL) in radar systems, new methods for data analysis enter the world of radar technology. With the maximum likelihood method, the reasoning of probabilistic analysis and big data enters the game.
Moving Target Indication
Moving Target Indication is one important method to discriminate targets against clutter. But the algorithms go beyond simple visual display. The form the basis for automatic detection, tracking and reasonning. The white papers and case studies suggest applications in military and civil contexts.
Multi Target Tracking
Tracking several targets in the same time implies challenges to visualisation but also to the control of the actual radar antenna. Recent research sheds light how to expand range and quantity.

Phased Array Radar Systems
Phased Array Antennae offer large scope for exploitation in radar technology, such as beam forming and steering. This section provides an insight into new applications but also into new design approaches.
Pulsed Radars
There is many different variants existing of pulsing a radar wave, all depending on the specific goal and expected outcome of an application. With the growing variety of radar applications, also the variety of pulsation approaches grows. This section tells you more.
Pulsed Noise Radars
A specific design of radars are pulsed noise radars. Those radars follow the simple approach of starting with a pseudo-random noise that is subsequently formed into specific wave forms. This approach allows for many different applications.
Radar and Health
The potential correlation of high levels of microwave radiation and negative health impact is worrying. The section talks on general impact of electro-magnetic waves. Apart from papers talking about radar impact on health, this section also includes applications for medical analysis, using radar technology.
Radar Cross Section Measurement (RCS)
This section is pretty straight forward. What are the novelties for catching and analysing a target’s cross section (RCS). Analysis looks at transceiver and antenna design as well as on the analytic and compute side of the radar.
Synthetic Aperture Radar (SAR)
SAR makes use of radar images, taken in motion of the radar source and integrates the results into one image of higher spacial resolution.
SESAR stands for Single European Sky ATM Research. It is a collaborative project to reorganize the European Airspace. SESAR has the goal to make flying more economic (more passangers transported at less costs), saver and more environmentally friendly (less CO2 emission, less fuel consumption). The concepts and technologies behind, mandated by EUROCONTROL, now find application all over the world in civil and military air traffic control. The idea of a flexibilized, air traffic with adaptive routes managed by interconnected air traffic agencies in various countries is promising and has much unexploited potential.
Spectrum Analysis of Radar Signals
This section introduces new methods and approaches to spectrum analysis of radar signals.
Statisctical Methods in Radar Signal Processing
Computer technology allows for increasingly sophisticated analysis of data. This section introduces into the most recent research results on the subject.
