Packed in an autonomous, compact package, EL/M-2055
tactical airborne recce system, provides Synthetic Aperture Radar
(SAR) or Moving Target Indication (MTI) functions, effectively and
rapidly covering wide areas of ground. The UAV payload includes the
radar sensor and integral signal processor which processes the raw
radar signals to create photographic quality images of the scanned
area, operating under all weather and visibility conditions including
clouds, heavy dust, fog, smog and moderate rain, day and night. These
pictures are sent with metadata, via data-link to the Ground
Extploitation Segment (GES) where image intelligence (IMINT)
interpretation is performed.
SAR provides an effective, long range, wide area
reconnaissance means offering high resolution imaging and flexible
area geometry. SAR images are usually delivering a "flat" view of the
area, even at very long distances. The mission planning and control
enables real-time management of the mission and on-line re-tasking
during the mission. The SAR generally operates in three distinctive
operating modes – STRIP, SPOT and GMTI.
STRIP mode enables rapid coverage and mapping of a large
area from a distance from few tens of kilometers to over 100km. The
area coverage rate depends on the resolution which determines the
level of details required for interpretation and target detection.
Usually, STRIP mode resolution is set at 3 to 1 meter level,
considered as sufficient for target detection and overall assessment
of an entire region. SPOT mode is equivalent to the narrow field of
view of an imaging sensor. It offers detailed examination of a
designated area of interest, at "sub meter" resolution level. Such
levels are ranging from 60 to 30 and even 10 cm. This mode provides
very detailed images at qualities adequate for target classification.
Moving Target Indication (MTI) mode is employed when
automatic detection and tracking of moving targets is required. This
mode can be used to cover a specific sector and trigger automatic
alert when suspicious activities (movements) are detected in a
designated area, or for tracking of known elements as they move along
known routes or through a large area (such as armor units, air defense
assets or logistical convoys) MTI can cover specific sectors or an
entire 360 degrees.
