Abstract
This paper conducted research on the super close-in PD radar's complex target echo synthesis technology, and put forth a method of "Video synthesis combining space synthesis". The method divided the work space of radar and complex target into multi-small airspace based on equal space angle during the process of simulation. In accordance with the principle of scatter-points distribution, and made dynamic distribution of target scatter-points to the airspace on the basis of known cross posture. During simulation, target scatter-points' echo of the same airspace will carry out video synthesis, then are sent into radar by I/Q modulation and up-conversion. In the mean time, all airspaces' echo will undergo space synthesis again through array antenna, echo signal will finally be generated to radar receiver antenna.
