Radar receivers are usually, but not always, in the same location as the transmitter. The reflected radar signals captured by the receiving antenna are usually very weak. They can be strengthened by electronic amplifiers. More sophisticated methods of signal processing are also used in order to recover useful radar signals. Two of the most commonly used types of radar transmitters on the market today is Guided Wave Radar and Non-Contact (pulse) Radar. Guided Wave Radar (GWR) uses a probe to measure to guide high frequency, electromagnetic waves as they travel down from a transmitter to the media being measured. Non-Contacting Radar sends down an electromagnetic wave

Radar Course JSH -16 Summary • Phased array provides improvements in radar functionality and performance – Beam agility – Effective radar resource management – Graceful degradation with module failures • Current trend is towards active arrays with distributed T/R modules – Large number of distributed active components and control – Radar astronomy differs from radio astronomy in that the latter is a passive observation and the former an active one. Radar systems have been used for a wide range of solar system studies. The radar transmission may either be pulsed or continuous. The strength of the radar return signal is proportional to the inverse fourth-power of the distance. Phased arrays have been built at many frequencies, but the classic radar band is X-band (8 to 12 GHz) so this is where most T/R modules operate. T/R module block diagram. We'll describe some of the functions that are required within a T/R module here. An active electronically scanned array (AESA) is a type of phased array antenna, which is a computer-controlled array antenna in which the beam of radio waves can be electronically steered to point in different directions without moving the antenna.
