Summary form only given. The capabilities of modern military multifunction/multi-mission/multi-role radars cannot be fully realised by using older sensor control strategies, due to the advance in radar technology and the complexity of the tactical environment. The most obvious radar management imperative is the real-time optimisation of radar functionality & radar resource management to meet the...
Chaff, a typical passive deceivable interference, is commonly used to cheat radar reconnaissance by producing high fidelity echoes in military counter-mission. It is difficult and challenging to distinguish chaff from ship based on their echoes. Firstly a sparseness characteristic analysis is implemented about ship and chaff return in time-domain and frequency-domain, respectively, which conclude...
This paper presents new developments and perspectives in phased arrays radars and electronic warfare for the next generations of T/R modules (medium/long term), in order to decrease the mass production cost, while increasing the level of performance and reliability. In terms of physical architecture, even if the brick one is more current at mid-term, the tile concept is investigated for conformal...
The Euroradar consortium has successfully developed and demonstrated an AESA technology upgrade for the Eurofighter Typhoon Captor radar. This technology demonstrator, designated CAESAR, enables E-scan capability to be fully exploited by the existing Captor radar, while retaining all features and capabilities of the original system. Advanced waveforms, designed and optimised for electronically scanned...
In the 90s, Galileo Avionica (GA Radar Systems Business Unit) has developed the GRIFO Radar, a multimode-multirole pulse Doppler radar, devoted to occupy an important role in the family of the radar for weapon release. In the last 15 years more than 400 units have been sold to five Air Forces, for more than 100,000 hours of operative flights. The need for the implementation of high-resolution modes,...
COSMO-SkyMed is the Italian Remote Sensing programme which foresees the utilization of a constellation of four SAR Satellites in Low Earth Orbit, dedicated to the management, control and exploitation of Earth resources for civil and defence applications. The program is completely funded by the Italian Government, mainly through the Italian Ministry of Research (MIUR) and the Ministry of Defence (I-AD)...
Helicopter classification capability is a desirable feature on air defense radars, as a way of distinguishing friends of foes. However, it is still a challenging task for any radar system. The classical method for helicopter classification is the L/N-quotient method, where two signal features are measured: time between peaks and blade tip velocity. Unfortunately, these features are difficult to measure...
High-performance radar networks have been deployed for homeland security Applications. Having the radars on a network allows for increased coverage via multiple radars, as well as the communication of situational awareness in real time to multiple remote users. The radars and networks exploit commercial-off-the-shelf (COTS) technology to be easily affordable for the wide-area surveillance needed for...
An algorithm for scheduling tasks for an air and missile defense radar is proposed. The algorithm consists of two sub-algorithms: a task interleaving algorithm followed by a distributed greedy scheduling algorithm. The interleaving algorithm efficiently interleaves range-unambiguous and range-windowed tasks (such as BMD-track tasks) based on knowledge of the task dwell characteristics. The output...
Earth observation from space devoted to civilian users are typically characterized by a variety of needs spanning from the mapping of very large areas of mid resolution up to higher resolution images (metric or even sub-metric) taken on narrower scenes. These needs are even more stringent when considering the defense use of the space observation, which typically require: 1) very high flexibility in...
The progress of the late time response (LTR) method applied to the detection and identification of body-worn hidden weapons has been discussed in [1] and [2]. Efficiency of the target signature extraction and its correct interpretation depend on the system subcomponent characteristics as well as the processing algorithms used. Peculiarities in frequency domain (FD) measurements based on a stepped...
This paper focus on the M3R active electronically steered antenna (AESA) system and will describe how this AESA is a step towards a fully digitized antenna with a receiver and an A/D-converter behind every antenna element and a full digital beam forming without using analogue sub arrays. First, it will be explained why extended air defence (that is Air and Missile Defence) requires a multi-function,...
