چکیده
A novel power amplifier unit for a phased array radar with 2 × output ports vacuum electron device is proposed. Double parallel connecting microstrip meander-lines are employed as the slow-wave circuits of large traveling wave tube operate in Ka-band. The high frequency characteristics, transmission and beam–wave interaction processes this simulated optimized. For each port one channel, simulation results reveal that power, saturated gain, 3-dB bandwidth can reach 566 W, 27.5 dB, 7 GHz, respectively. Additionally, amplified signals four have favorable phase congruency. After fabrication assembly, tests 80-period model performed preliminarily. tested “cold” S-parameters match well values. This type integratable combined has broad application prospects field on millimeter radar.

A Millimeter-wave Phased Array Radar for Hazard Detection and Avoidance on Planetary Landers
Safe, precise landing in difficult planetary terrain, including areas that are rocky, heavily sloped, or both, requires remote sensing of the surface in order to choose an appropriate landing site. While active or passive optical sensors might seem appropriate for this application, we are developing an alternate approach based on a millimeter-wave electrically scanned phased array radar. A rada...
متن کاملCoupled-Oscillator Phased Array Systems for Millimeter Wave Applications*
An array of oscillators coupled through mutual injection locking on a nearest neighbor basis has the property of automatically adjusting itself to linear phase progression across the array in response to appropriate adjustment of the elements at the edge of the array. This mechanism is well-suited to phase generation for phased array antennas at millimeter wavelengths because it obviates the to...
متن کاملBroadband Millimeter-wave FMCW Radar for Imaging of Humans
We present design and realization of a broadband FMCW Radar working in the Millimeter-Wave (MMW) region. The usable frequency range lies between 91GHz and 102GHz. We use a homodyne radar setup. Thus only one MMW source is necessary which is used for TX and LO generation simultaneously. The complex RX radar signal is calculated by a Hilbert transform in order to avoid a broadband MMW IQ mixer. A...

A hybrid array configuration suitable for wideband millimeter-wave applications is presented in this work. The proposed structure is based on the use of circular waveguide elements electromagnetically coupled trough circular apertures to a stripline distribution network. The adopted excitation mechanism avoids the use of transition components generally reducing the overall antenna efficiency. S...

The U.S. government operates seven radar networks providing weather and aircraft surveillance for public weather services, air traffic control, and homeland defense. A next-generation, multifunction-phased-arrayradar (MPAR) concept has been proposed that could provide enhanced weather and aircraft surveillance services with potentially lower life-cycle costs than multiple single-function radar ...
