By using the sensor array or the antenna array, the time domain sampling can be turned into time-space domain sampling, and the time frequency can be turned into space frequency (angle), then some time-domain signal processing fruit can be extended to space domain. A brand new area of signal processing is brought—array signal processing. Along with the prospering of the micro-electronics technology, digital signal processing and parallel processing technology, the theories and application of array signal processing also have some improvement, its application range keep extending, due to the further study of relevant researches.In this paper, we aim to do some researches on the following problems and proposing some resolutions by taking advantage of space-time joint adaptive array signal processing technology: the digital equalization technology of wide-band adaptive array channel is researched, and a scheme of channel adaptive equalization is proposed; the wideband time-space joint reduce-rank technology is researched, and a way of reduce-rank is proposed on the hardware; high-resolution-two-dimensional technology is researched and an improved MUSIC algorism is given to realize high-accuracy azimuth measuring, the azimuth measuring of relevant signal and the gain of feeble signal. A method which base on the frequency-angel joint estimation is proposed to realize the parameter estimation on the wide-band. The high-speed data transporting, multi-channel data synthesizing technology are also researched, the high-speed A/D and data transporting model and integrated sampling clock model to fulfill the high-speed transporting and multi-channel data synthesizing.
