Application of anti-jam antenna based on space-time signal processing

The technology of space-time signal processing can analyze the property of input signal in special and time-domain. Space-time configuration can greatly promote the freedom of the array antenna in order to raise the number of anti-jam without increasing the number of element of antenna. Especially, it improves capability of satellite receiver for suppressing broadband interferences. Paper puts forward a space-time least-mean-squares (STLMS) algorithm based on space-time signal processing. The algorithm can adaptively estimate the weighting vector of elements of antenna with a low computational complexity. The result of simulation demonstrates the STLMS algorithm can well reject the interferences and protect satellite signal.
