The invention provides an amplitude and phase test system of active phased-array radar T/R assemblies, and aims at providing the amplitude and phase test system of high efficiency, reliability and test precision. The N T/R assemblies are connected to antenna directional couplers via two paths of test feed power dividing networks respectively; a frequency synthesizer, a pre-stage power amplifier, a sum and difference device, a sum circuit receiver and a test conversion module are connected between the test feed power dividing networks at the front and tail ends respectively; when test starts, a terminal in the emission T test or reception R test mode emits a test instruction to the frequency synthesizer, the frequency synthesizer outputs test start and test pulse signals, and identical test excitation signals are generated in each beat according to the test pulse; and a wave controller controls different paths of phase shifters on the basis of an orthogonal coding rule, orthogonal phase modules is carried out on the test excitation signals respectively, the modulated signals are input to a signal processor, and amplitude and phase test for all the T/R assemblies is completed.

The invention discloses a wave control architecture integrating work and test simulation and a wave control method. The architecture mainly comprises a controller area network (CAN) bus interface module, a field programmable gate array (FPGA) module and a digital signal processor (DSP) module. The CAN bus interface module comprises a first CAN bus interface unit and a second CAN bus interface unit; the FPGA module mainly comprises an order analysis unit, a transmitting unit, a wavefront monitoring unit and a first simulation debugging unit; the DSP module mainly comprises a preprocessing unit, a second simulation debugging unit and a calculation unit; and the storage module mainly comprises a stationary storage unit and a dynamic storage unit. The entire wave control system adopts the DSP module and the FPGA module as main processing devices, the system is connected with a system debugging platform through a joint test action group (JTAG) interface, and the online debugging of the entire system is realized through the first simulation debugging unit and the second simulation debugging unit. Due to the adoption of the architecture and the method, the problems of the wave control software that a simulation test program needs to be run again in the debugging process can be solved, and the working efficiency is improved.

The present invention relates to a phased array antenna (10) with an electronically variable antenna diagram, wherein control signals for at least two phased antenna elements (13) are processed for a broadcast transmission and are broadcast to the phased antenna elements (13) via a wireless medium or using feed lines for the useful signal component of the phased antenna elements in a frequency band differing from the frequency band of the useful signal components As a result of the use of the broadcast transmission method in a different frequency band, there is no need for any additional signals and lines for the array antenna and the complexity of the array antenna can be reduced and the flexibility and reconfigurability can be improved

Die vorliegende Erfindung betrifft eine phasengesteuerte Gruppenantenne (10) mit elektronisch veranderbarem Antennendiagramm, wobei Steuersignale fur mindestens zwei phasengesteuerte Antennenelemente (13) fur eine Broadcast-Ubertragung verarbeitet und zu den phasengesteuerten Antennenelementen (13) uber ein drahtloses Medium oder unter Verwendung von Zufuhrleitungen fur Nutzsignalkomponente der phasengesteuerten Antennenelemente in einem vom Frequenzband der Nutzsignalkomponenten abweichenden Frequenzband rundubertragen werden. Durch die Verwendung des Broadcast-Ubertragungsverfahrens in einem abweichenden Frequenzband sind keine zusatzlichen Signale und Leitungen fur die Gruppenantenne erforderlich und die Komplexitat der Gruppenantenne kann verringert und die Flexibilitat und Rekonfigurierbarkeit verbessert werden.
