ACUNA TAMAYO, Eciel et al. Design of the generation module and matched filter for pulsed compression radar. EAC [online]. 2022, vol.43, n.1, pp.33-46.  Epub 11-Jun-2022. ISSN 1815-5928.

The present work deals with the use of biphasic codes for their application as an exciting signal in pulse compression radars. Its main characteristics are exposed and the digital design of sections for modulation, reception and compression is described. Very High-Speed Integrated Circuit Hardware Description Language (VHDL) was used for its implementation and MATLAB® for simulation, modelling and synthesis in VHDL of functional blocks. A 32-bits code is used with witch a 20.56 dB Peak to Sidelobe Level Ratio (PSR) is guaranteed. The contribution of the proposal lies in the demonstration of two convolution synthesis methods for the BPSK signal. Is presented and described its finite difference equation that define both of the convolution methods and also presented main resources used for their synthesis on DE10-Standard Development Kit.
