“…With the early new electronic devices capable of shifting the phase of analog signals, the use of phased-array antennas to detect targets has become feasible. The main advantage of this approach is to reduce at least ten fold the time to scan the entire sky [2]. Electronic scanning is attained by changing the phase and amplitude of each array element, which are regularly spaced by a distance of λ/2, where λ is the corresponding wavelength of the operating frequency.…”

The purpose of this paper is to derive a general analytical expression for the correlation coefficient of signals received by two different antennas as a function of the distance between them (baseline distance), the signal bandwidth, and the antenna beamwidth. The two antennas are supposed to be part of a radar system for detecting meteorological phenomena such as rain and clouds. One of the antennas transmits the radar signal and receives the echoes; the other antenna only receives the echoes. The good functioning of such a radar system depends on the correlation between the two antenna signals. The exact analytical framework derived here has been recently used in practice to assist in the design of a meteorological radar system for Orbisat Indústria e Aerolevantamento S.A.

“…These present hazards for aircraft, especially when taking off or landing. These windshears or strong downbursts are especially dangerous to aircraft [29,30,31]. Through appropriate configuration of the phased array radar at the NWRT, it can be designed to provide this windshear information [29,30,31,32,33].…”

“…These windshears or strong downbursts are especially dangerous to aircraft [29,30,31]. Through appropriate configuration of the phased array radar at the NWRT, it can be designed to provide this windshear information [29,30,31,32,33]. Detecting windshear is a classic problem for aircraft, but our work will also provide an image of the atmosphere surrounding the radar.…”

“…This will provide aircraft and other vehicles in the future an ability to make reasonable short term weather forecasts and improved situational awareness. Prior to collecting the weather data, it is imperative that the transmit waveforms of the phased array antenna be properly designed for this activity [30,32,33], which does include pulse compression. Similar to current work on the conventionally rotating WSR-88D, staggered pulse repetition times (PRTs) will also be explored to improve the data quality and increased scan rates [34].…”
