Develop innovative radar-based imaging approaches to perform long-range battle
damage assessments of ships.
The timeliness, accuracy, and completeness of battle damage assessments (BDA)
is critical to the success of any military engagement. BDA have traditionally
utilized relatively short-range optical sensors onboard aircraft operating in
close proximity. However, the safe airspace access required to observe the
target at close range is not possible in anti-access/area denial situations.
BDA utilizing long-range radar tracking and imaging is an alternative. Radar
does not provide the level of high resolution and high definition consistent
with human visual characteristics. As a result, there is a need for innovative
approaches to extract comparable information from radar returns for the BDA of
ships at sea from ranges that may exceed 50 nautical miles (nmi). Gross changes
such as the vessel going dead-in-the-water or rotating antennas ceasing
operation are easily discernable with radar. More challenging is determining if
the vessel is listing and what type of external structural damage has occurred.
Advances are needed in single and multi-channel inverse synthetic aperture
radar (ISAR) imaging techniques. Advantages of interferometric ISAR should be
considered, as some fielded radar systems are capable of supporting that mode.
Consideration should be given to scenarios that allow imaging to be underway
immediately prior to weapon impact, at the time of the impact, and at various
times after impact. Transition of this product is to be as an appliance within
the Navy’s Minotaur control application.
Utilize self-generated simulated data to develop single and multi-channel
(possibly interferometric) ISAR imaging approaches capable of providing ship
BDA comparable in respects to that possible from short-range (20 km or less in
mid-latitude oceanic environments) visual imagery. (Note: While computational
resource restrictions will not be imposed in Phase I, the product will
ultimately be hosted on existing Navy maritime surveillance platforms such as
the P-8A, MQ-4C, MQ-8B and MH-60R.) The Phase I effort will include prototype
plans to be developed under Phase II.
Further design and develop the concept identified in Phase I. Working with the
sponsor, prepare an at-sea airborne radar collection plan for use during a Navy
live fire missile exercise involving a target ship and remote airborne
collection platform. Utilize the collected data to mature the techniques
explored in Phase I. Provide a complete assessment of the approaches and
develop a transition plan.
DUAL USE APPLICATIONS: Mature the algorithms to be suitable for transition to
Navy maritime surveillance radar systems or as a capability within the Navy’s
Minotaur control application. Possible dual use applications include long-range
ship imaging and status assessment by organizations like the Coast Guard or
possibly commercial radar satellite providers.
