“…When M reaches the limit value at which the azimuth beamwidth of the subarrays equals the angular sector (2 π / M ), instantaneous 360° illumination is obtained and the full circle may be used for near-range surveillance or for the tracking of many close-up or pop-up targets. A similar omnidirectional operation (called “staring” or “ubiquitous”) may be attributed to some short-range operational radars, such as the sectorial-coverage ALARM © [11, 12], while the cylindrical/conical array is used in other short-range systems, mainly against rockets, artillery and mortar, such as the L-band Lightweight Counter Mortar Radar (LCMR-A or AN/TPQ-49, AN/TPQ-50); see [13] ( )). An S-band, ubiquitous radar (probably not yet operational) called “Omni-directional Weapon Locating – OWL – radar” and using a circularly symmetrical array, is described in ().…”

Multifunction radars based on active phased arrays are well known and widely studied systems. The concepts of bistatic architecture,\ud conformal array and digital beam forming (DBF) are combined in this paper to define a novel multifunction radar for\ud point defense. The conical shape of the antenna overcomes the significant limitations in the azimuth coverage of 3608 of fixedfaces\ud phased arrays due to the beam scanning up to 458. The usage of separate transmit/receive arrays and the DBF technique\ud adds the operational flexibility and the possibility of multiple simultaneous functions, with an optimal time-energy resources\ud exploitation. After a short description of its technological demonstrator, some significant design trade-off, and operating\ud aspects of the proposed architecture, called d-Radar, are described, showing the main differences with respect to the classical,\ud four faces, and phased-array multifunction radar architecture. It is described how the operating modes can be made more and\ud more similar to a “staring” or “ubiquitous” radar permitting an instantaneous detection and location of short-range, lowelevation\ud targets for sea and ground operations. Finally, some remarks about the resources management and scheduling\ud are shown with the results from a case of study

“…Persistent uninterrupted streams of target detections provided from coincident multiple sectors allow effective tracking of targets following irregular tracks, when obscuration is possible. Persistent streams of data also allow processing techniques such as bladeflash signature recognition techniques and micro-Doppler processing to be implemented [5], which are required for effective discrimination and recognition. This is particularly important as the targets become smaller and slower and the probability of confusion with birds becomes greater.…”

UASs (Unmanned Air Systems) are universally used in many activities, spanning from leisure-commercial to military applications. Accordingly, as the number of UASs operating in the sky increases, so does the need to detect and identify them, in order to ensure their legitimate use. This paper introduces a continuous wave (CW) Doppler radar implementation that can be used to provide early warning for flying-by small UASs. By applying Fast Fourier Transform (FFT) to the returned signal’s Doppler frequency, estimations can be made regarding the presence of aerial bodies inside an Area of Interest (AoI). Achieving reliable detection with a low false alarm rate (FAR) while keeping the size and power demands of the system to minimum was a challenge that was successfully met. The proposed system was extensively tested in outdoor environments; measurement results are presented and parameters such as radar power, antenna gain, and noise are discussed.

Applications of staring surveillance radars

Abstract: Staring surveillance radars have the potential to offer significant advantage in the detection of some hitherto difficult to detect targets. This paper sets out the advantages of staring radars and gives two examples where they have demonstrated unique capabilities.
