Correlation properties of Gaussian FSK/PSK radar signals

Hybrid radar signals which are simultaneously frequency-shift-keyed (FSK) and phase-shift-keyed (PSK) are investigated with regard to their range correlation properties. The firing order of the discrete frequencies within a single burst is selected at random from a pseudo-Gaussian distribution. The...

Zusammenfassung:Hybrid radar signals which are simultaneously frequency-shift-keyed (FSK) and phase-shift-keyed (PSK) are investigated with regard to their range correlation properties. The firing order of the discrete frequencies within a single burst is selected at random from a pseudo-Gaussian distribution. The range correlation properties of FSK and FSK/PSK signals are illustrated using computer simulations of the autocorrelation functions of several representative signals. It is observed that the range sidelobes of the autocorrelation function associated with a Gaussian FSK signal can be improved through the application of a pseudo-noise bipolar PSK sequence.< >
