A digital phased array antenna comprises a plurality of antenna elements, each element receiving an incoming signal. An analog-to-digital converter is coupled to at least one of the antenna elements to convert the incoming signal to a multi-bit digital signal. A demodulator or de-ramp circuit ...
Figure 1.Phased Array Beamforming You can implement the time delay compensation and summation in the digital domain by using high-speed Analog to Digital Data Converter (ADC) to capture the antenna elements’ signals. The Phased Array (PA) here, is known as the Digital Phased Array (DPA). ...

Recent developments in latching ferrite phase shifters permit phase control within 360 degrees at microsecond switching times for phased-array antenna elements. When an array antenna must handle large instantaneous signal bandwidths, the simple modulo 2/spl pi/ phase control provided by these phase ...
array. This class of algorithms is often referred to as beamforming (BF). The name beamforming is borrowed from an analogy with phased array antenna technology, where a radio “beam” is formed from the emission of an antenna array focused in a certain di...
The phased array spread-spectrum system steers an antenna beam formed by the first antenna11and the second antenna12in the direction of the strongest multipath. This function can be performed continually, so as to be continually looking for the optimal multipath. This beam steering can be done ...
