Multi-channel array manifolds are required for wideband AESA applications. In modern solid-state AESA arrays, MMIC-based T/R modules generally utilize digitally-controlled phased shifters to steer the beam on transmit and receive. The given phase value is only accurate at one frequency, and so for wide bandwidths of several hundred MHz (at X-band for example), the beam does not get formed properly ...

Key obstacles to extending OFDM to wireless links and networks at high-frequencies and dynamic channels are inherent low performance to Doppler and power amplifiers operation with high back-off. Other significant obstacles are multipath and impulsive noise. PEARL-OFDM combines a layered architecture with technologies that mitigate such obstacles and enable full-range rates that maximizes connectiv ...

The longstanding tradition of using lines to moor ships to docks is inherently labor intensive and hazardous. Synthetic line snapback, limbs caught in rigging, as well as failed deck fitting projectiles, have maimed and killed many shipboard and dockside personnel over the years. Likewise, the challenges associated with shortening, slacking, doubling up and singling up lines to adjust for changing ...

The proposed Mobile Port concept, consists primarily of a modular and rapidly deployable Floodable Jetty dissipate the required Pierson-Moskowitz Sea State 5 (SS5) energy, without any additional stabilizing anchors. Within the Jetty’s lee, the Lightweight Modular Causeway System (LMCS) that has been under development by the US Army Corps of Engineers, Engineer Research & Development Center (ERDC ...

The Navy needs technology to convert the energy content of high-speed impinging jets on aircraft carrier flight decks into useful power. We propose to develop an Active Heat Spreader (AHS) to meet Navy needs. DARPA is developing heat spreaders to remove the concentrated energy from impinging jets on Navy flight decks. Our AHS removes the concentrated energy and uses the removed energy to generate ...

The Navy needs robust high-speed rotary unions for advanced liquid-cooled and high-temperature-superconducting (HTS) generators. We propose to develop hydrostatic bearing/seal rotary unions (HBSRUs) to meet Navy needs. Hydrostatic bearings can operate at large radii with fast rotational speeds, so our HBSRUs have room for large flow capabilities. The hydrostatic bearings offer the same advantages ...

The design and development of piezocrystal sonar transducers is a challenging multidisciplinary and technological effort that spans many fields and skill sets. We look to extend and improve our transducer assembly technologies to reduce cost and implementation time for sonar technology transition and in particular our methods for Active-Passive single crystal ring development and fiber glass wrapp ...

Addressing the water purification needs of the Army in a lightweight and compact system is not trivial given the diverse range of waterborne contaminants that could potentially be found on the battlefield. Based upon Cascade Designs expertise at developing individual water purification systems for the military and outdoor markets, we are proposing a novel in-line filter design that is based on inc ...

In order to improve the safety and efficiency of navy high speed small boat operations, FarSounder proposes a 3-dimensional, forward looking sonar solution capable of simultaneous bathymetry sensing and obstacle detection out to ranges of at least 1640 ft (500m). Additionally, the system will be cable of 50 knot operation and suitable for installation on a high speed planing vessel such as common ...

We propose to develop a lightweight deployable array to enable nanosatellite-scale spacecraft to reliably deploy large-area solar arrays and antenna arrays to enable these small satellites to perform missions requiring high power and/or high gain communications. Although launch opportunities for smaller scale spacecraft are becoming much more common, the supporting subsystems required to utilize t ...
