WebMultifunction Phased Array Radar (MPAR) was an experimental Doppler radar system that utilized phased array technology. MPAR could scan at angles as high as 60 degrees in elevation, and simultaneously track meteorological phenomena, biological flyers, non-cooperative aircraft, and air traffic. WebActive Phased Array Radar ( APAR) is a shipborne active electronically scanned array multifunction 3D radar (MFR) developed and manufactured by Thales Nederland. The radar receiver modules are developed and …
WebAs it is observed, the secondary major lobe, denoted by grating lobe in Fig. 1(b), appears around θo= -45°. By utilizing the null and the radiation-matched pattern of the antenna … In antenna theory, a phased array usually means an electronically scanned array, a computer-controlled array of antennas which creates a beam of radio waves that can be electronically steered to point in different directions without moving the antennas. In a simple array antenna, the radio frequency current from the transmitter is fed to multiple individual antenna elements with the proper phase relationship so that the radio waves from the …
WebTo better understand the virtual array concept, first look at the two-way pattern of a conventional phased array radar. The two-way pattern of a phased array radar is the product of its transmit array pattern and receive array pattern. For example, consider a 77 GHz millimeter wave radar with a 2-element transmit array and a 4-element receive ...
