摘要：
The requirements for high resolution, long range ISAR imaging systems capable of recognising targets have been outlined. Systems meeting these requirements and operating at mm-wavelengths have been proposed. The systems consist of N phased locked transmitters feeding as many antennas in phase. Quasi-optical power addition at the target occurs. In the receive mode all antennas are connected in phase. These systems can at least double the range obtained by utilising a system having one transmitter/antenna combination. Several realisation options have been studied including the annular synthesis antenna systems which offer some advantages over more conventional realisations.
