Multi-channel spatio-temporal two-dimensional adaptive filtering technology and time domain frequency domain two-dimensional constant false alarm detection technology is an advanced signal processing technology in airborne phased array radar. When implemented in space-time two-dimensional radar signal processor, the circuit is complex , Large amount of computation, especially in the space-time two-dimensional adaptive filtering of data buffer memory circuit, the access format is complicated.Therefore, in the realization of space-time two-dimensional adaptive filtering and time-domain frequency domain two-dimensional constant false alarm detection technology, sufficient The use of programmable logic devices, not only can improve the design flexibility, reliability, but also can reduce the size.
