This paper presents an RF module including a signal generator for an APAA. By generating an RF signal independently in each module and sharing them among antenna arrays, the APAA realizes multi-frequency and multi-modulation beam forming simultaneously. The RF module measures the output RF signal of itself to compensate errors of output timing, amplitude and phase of the RF signals between multiple...
<?Pub Dtl?>This paper presents a new concept of an active phased array antenna (APAA) system with RF modules, including an RF signal generator. The proposed APAA realizes multi-frequency and multi-modulation beam forming simultaneously by generating an RF signal independently in each module and sharing them among the antenna arrays. This configuration is effective in a distributed array radar...
We propose a new concept of an active phased array antenna (APAA) system that realizes multi-frequency and multi-modulation beam forming simultaneously in an array. The proposed APAA system consists of RF modules including an RF signal generator. A distributed array radar system with the proposed configuration can be simplified by not transmitting a signal in RF at the interconnect equipments of modules...
