The first article introduces the use of a compensation type of non-coherent model sidelobe suppression filter SSF and actually develops the theoretical calculations and experimental results associated with 13 place barker code pulse compression sidelobe suppression. Compensation type non-coherent models of SSF opt for the use of least square approximate inverse filtering techniques for designs if the subpulse width is 0.7 microsecs and the peak sidelobe values do not exceed -30db. The second article puts forward a heirarchical type of decentralized information processing wave filtering algorithm. In conjunction with this, going through studies of actual cases, it does research on applications of the algorithm in integrated navigation or guidance systems. the special point with this type of algorithm is that the amount of calculations associated with main or global wave filters is small. Measurement calibration only involves addition and subtraction operations. It is particularly suitable for integrated navigation or guidance systems which have relatively high sampling frequencies and relatively long feedback calibration intervals.
