phased array

 (fāzd)
n.
An arrangement of dipoles on a radar antenna, in which the phase of each dipole is controlled by a computer so that the beam can scan very rapidly.

phased array

n
(Astronomy) an array of radio antennae connected together to form a single antenna. The beam produced can be steered across the sky by adjusting the phases of the signals. The absence of moving parts enables the beams to be steered very rapidly, making it useful in radar

Consider an airborne radar equipped phased array antennas. The number of transmitting antennas and number of receiving antennas are M and N, respectively.
There are many challenges associated with the test and calibration of phased array antennas. The more elements that make up the array, the longer the time it takes to fully characterize the antenna.
In the field of array antennas synthesis, the deterministic use of the feeds' size in order to fulfill given power pattern constraints represents an innovative idea.
Design and test engineers will find RH cable ideal for intermodulation and low noise measurement, flexible VNA/PNA test ports, phased array antennas, RFI and EMI test sites and various precision test and measurement applications.
For a number of extremely practical reasons, phased array antennas are becoming increasingly important to the field of electronic warfare (EW).

To counteract possible threats, high performance systems with phased array antennas have been offered [4-8].
The author has organized the main body of the text in seven chapters devoted to substrate integrated circuits, substrate integrated feeding networks, substrate integrated slot array antennas, and a wide variety of other related subjects.
After that, lots of works about the aperture coupled microstrip array antennas had been carried out with good array performances achieved [17-20].
On the other hand, slots are widely used as radiating elements in waveguide array antennas in the whole microwave range [4-9].
His topics are antenna system-level performanceparameters, vector analysis, radiated fields, dipole antennas, loopantennas, aperture antennas, and array antennas.
Fenn (Advanced RF Sensing Group, MIT Lincoln Laboratory) notes that adaptive microwave phased array antennas are known for their ability to improve performance in radar and communications systems.
