Abstract EN
In a broadband adaptive array antenna with a space-time filter, a delay filter is required before digital beamforming when the Frost algorithm is used to obtain the weight vector.
In this paper, we propose a Farrow structure instead of a direct form FIR structure to implement the time delay filter since it can satisfy the demand for real-time update and is very suited for the FPGA platform.
Furthermore, a new off-line algorithm to calculate the Farrow filter coefficient is presented if the filter coefficient is symmetric.
Finally, simulations are presented to illustrate that the design methodology for the Farrow filter is correct.
The simulations also prove that the Frost broadband adaptive antenna effectively mitigates the interferences with a Farrow filter.
