![]() ![]() These antennas are compatible with all Penetradar GPR systems and software. ![]() As shown in Figure 14.20, the effect of the two downwind elements in the widely spaced (left side) cluster is neutral - i.e. The 501B/401B/301B antennas are housed in a rugged plastic enclosure for high durability and incorporate removable wheels for maximum mobility. When the antenna elements are grouped in threes, the combined drag coefficient (based on the frontal area of one radome element) is greatly reduced. ![]() Uses for these antennas include detection of subsurface pipes and utilities, measurement of thick pavement layers, geotechnical applications including detection of underground storage tanks (UST’s) and for a wide variety of general site inspection applications. These antennas are a shielded, broadband dipole design that optimize bandwidth and minimize distortion resulting in superior subsurface detection capability. The Model 401B/501B can also be suspended from a vehicle in close proximity to the ground and when properly installed can be operated at speeds up to 35MPH (55km/hr). These antennas are optimized for ground contacting operation and can be pulled manually or towed by a vehicle. Integrators and radar manufacturers interested in evaluating MESA-X-EVU can connect their own Pulsed or FMCW transceivers through a single coax SMA port.Įchodyne has produced a limited number of MESA-X-EVU to share with qualified partners and integrators.The 2 nanosecond (500MHz) Model 501B, 2.5 nanosecond (400MHz) Model 401B and 3 nanosecond (300MHz) Model 301B are mid-frequency and low frequency contacting-type ground penetrating radar antennas with penetration depths of approximately 6 feet (2 meters), 9 feet (3 meters), and 12 feet (4 meters), respectively. The aperture is controlled through a simple USB 2.0 interface and requires only a single +12 DC source to operate. While this size and weight already demonstrates a vast improvement over traditional electronically scanning arrays, Echodyne will be decreasing this even further as the company optimizes the technology for various implementations. Fully assembled without packaging, the subsystem is a mere 50 x 18 x 2.5 cm with a total weight of only 1.4 kg. The MESA-X-EVU subsystem includes the metamaterial array, the array control driver circuitry, and the beam steering computer. The net effect of this simplified architecture is dramatically lower cost, size, weight and power.Įchodyne’s MESA-X-EVU operates at X-band and has a broad field of view (±50° in azimuth and ±45° in elevation) which it can scan very rapidly given its sub-microsecond beam switching speed. Netradar provides a unique end-to-end solution for collecting mobile network performance data, directly from customers’ phones. And unlike Phased Array radars or Active Electronically Scanning Array (AESA) radars that use complicated, expensive, and inefficient transmit/receive modules which include phase shifters, amplifiers, circulators, and low noise amplifiers behind every single antenna element, MESA uses a vastly simpler metamaterials architecture. Unlike conventional mechanical apertures which steer a radar beam using motorized gimbals, Echodyne’s MESA requires no moving parts to steer its beam. The total amount of energy radiated from a transmitting antenna can be measured in terms of a Radiation Resistancewhich is the resistance that, when replacing the antenna, at the feeder will consume the same amount of power that is radiated. “Metamaterials based radar has the opportunity to not only change how traditional, heavy, expensive radar systems are deployed but can open up new markets for advanced radar that were never before thought possible because of the cost, size and weight of traditional electronically scanned arrays.”Įchodyne’s MESA X-EVU combines ultra-low C-SWAP (cost, size, weight, and power) with ultra-fast beam steering (sub-microsecond) in an electronically scanning array that can be integrated into new or existing radar systems. “We are very pleased with the early reception of MESA-X-EVU by key partners and are excited to be able to offer more units to qualified partners and integrators,” said Eben Frankenberg, founder and CEO of Echodyne. The first product from Echodyne, a metamaterials electronically scanning array for X-band (MESA X-EVU) is now available for partners and integrators interested in evaluating MESA for radar systems in a variety of commercial markets including maritime, aviation, and surveillance/security among others. Echodyne’s MESA makes high performance radar far easier to deploy by lowering both the cost and weight by up to 10 or more times while decreasing the size of the antenna by up to 5 or more times over traditional electronically scanned arrays. Echodyne Brings First Metamaterials Based Radar Antenna to Marketīellevue, WA - Echodyne Corp today announced limited availability of its first metamaterials electronically scanning array (MESA) for radar applications. ![]()
