This paper discusses and shows how the range-time sidelobes of P4 pulse compression waveform can be substantially reduced by applying Kaiser-Bessel amplitude weighting function. Also, a comparison is made with classical amplitude weighting function (i.e. Hamming window) applied to the receiver waveform of 100 element P4 code. Effects of weighting on the Doppler performance of the P4 code are presented.
The numerical evaluation of a non-linear frequency modulation (NLFM) based on MATLAB code is presented. The results of the numerical evaluation are depicted in two-(autocorrelation function) or thee-dimensional plots (ambiguity function). The program makes a numerical approach in order to design a NLFM pulse based on the stepped frequency characteristic. The program could be used to optimize results...
