Total Technique Research on Phased Array Radar Seeker

Phased array radar seeker (PARS) has some merits such as agile beam scanning, controlled power time resource allocation and so on. Its makeup has two forms such as active phased array and passive phased array. In the active phased array every antenna unit has a receiver and a transmitting power amplifier. However, all antenna units share one or several transmitters and receivers in the passive phased array. Comprehensive consideration is needed when choosing system schema. Active phased array radar seeker is made up of phased array antenna, beam control computer, T/R module, stimulator, power divider, beam forming network, receiver, signal processing, data processing and central control computer, etc.
