A SOF Tactical Repeater will be a small, rugged, lightweight, programmable, easily deployed, software radio repeater that can be awakened via RF, by an authorized user, from a passive sleep mode. One or more antennae should be deployed away from RF shadowing, with line of sight to all users. In… More

Lambda Science's approach to radar detection and discrimination of small targets in high-altitude sea clutter is to utilize improved multi-scan processing algorithms that incorporate feature-aided multiple hypothesis tracking and real-time clutter modeling. A sophisticated multi-target track (MTT)… More

The objective of this SBIR is to develop (design, build, and test) and demonstrate real-time high-altitude, high-grazing-angle radar processing software to automatically detect and discriminate signatures associated with small maritime targets. Phase II will result in a near real-time… More

Active electronically scanned array (AESA) multi-function radar systems require resource management and scheduling to realize their full performance capabilities. Many tasks compete for resources. Some resources, such as the round trip propagation or waiting time are reusable (we can transmit in… More

Automated ship and small craft classification tools for ISAR imagery is a challenging problem, but the use of advanced time-frequency processing techniques in conjunction with proven methods from statistical pattern recognition hold considerable promise for realizing a sound capability. LSI's… More

Many current United States Navy (USN) OPSIT/TACSIT scenarios comprise demanding dynamic environments for airborne sensors. The ability to task or mode interleave with adaptive scheduling is essential to achieving desired sensor/mission effectiveness. Both active electronically scanned array (AESA)… More

Developing effective automated ship and small craft detection and classification tools for airborne radar systems is a challenging problem. Track before detect modes have been developed and implemented to mitigate the problem of false targets due to strong sea clutter returns. Recent studies such… More

The current state of the art in assisted target recognition separately processes individual image frames from different sensor modalities (e.g., ISAR and EO/IR) and forms a decision based on a weighted sum of classification confidence for each modality. The request for proposal (RFP) indicates that… More

The on-board and co-site EMI environment can be very severe for aircraft sensor and communications systems. The current state of the art in predicting on-aircraft RF performance and performance degradation from EMI (also known as co-site interference) utilizes physics-based modeling and simulation… More

Detection of small boats and semi-submersibles in the littoral environment is very challenging as a result of the very strong and persistent backscatter from the ocean surface. Detection modes that employ long dwell coherent processing are a promising approach to achieving reliable low false alarm… More

Surface vessel detection and classification from airborne platforms relies heavily on radar at operationally useful stand off ranges. Upon detection the radar search waveform may be used to accrue additional information about the surface contact for classification but confidence is likely to be… More

Detection and tracking of moving vehicles and dismounts across the land-sea boundary is very challenging because of the highly complicated dynamic heterogeneous littoral clutter environment. LSI proposes knowledge based adaptive signal processing techniques that will ultimately sense the dynamics of… More

Sensor exploitation management is a key enabling technology to optimally use the capabilities of airborne radar systems with and without an operator-in-the-loop. LSI proposes to develop this capability to compliment a sensor resource manager capability that when integrated will result in… More
