Programmable LFM Signal Processor.
Abstract
The linear frequency modulation signal processor may be programmed to be a matched filter for any pulse compression ratio less than or equal to the square of the number of bandpass filters. The processor is implemented by using a fast Fourier transform (FFT) for the filter bank. The implementation shown assumes digital processing at baseband using in-phase and quadrature (I and Q) channels and a FFT for the filter bank. The I and Q channels are fed through a sidelobe filter, a short input tapped delay line, and a set of M complex multipliers to the FFT. The FFT outputs are connected to a long tapped delay line through a second set of complex multipliers whose outputs are summed in the long tapped delay line summer. (Author)
