介绍了一种可以应用于星载和机载SAR 成像雷达的并行总线分时控制技术,通过在雷达并行总线上按约定时序传输模块地址码、参数控制码和同步控制码,较好地解决了雷达设备在模块多、控制量大以及时序要求严格情况下的控制问题,并降低了单纯并行总线控制时对总线容量的需求。该总线能够满足复杂的控制要求以及较小的设备量,适用于星载和机载等对质量有苛刻要求的平台。

A type of time-sharing control technique used in space-borne and air-borne radar parallel bus is described in this paper. Module address codes, parameter control codes and synchronization control codes in promissory timing are transmitted on radar parallel bus. It controls well in radar equipment in time of many modules, amounts of control and strict timing. Also it reduces the demand of bus capacity in time of parallel bus control only. The bus can meet the requirement of complex control and it requires a small amount of equipment. It is suitable for satellite borne, airborne and other platforms which have strict weight requirements.
