Introduction. Complicated signals with the button ambiguity function can provide the distance and speed of target independent estimation. These include the signal with the 2nddegree that has been carefully researched earlier.
Problem statement. The potential characteristics of 2nd degree, 3d degree and 4th degree frequency modulated probing signals are analyzed and compared.
Investigation of potential characteristics of 3d degree and 4th degree frequency modulated probing signals. Features of 2nd degree, 3d degree and 4th degree frequency modulated probing signals are considered. Comparison of these signals autocorrelation functions is held. Features of cross-correlation function splitting into two peaks and the consequences of this effect are considered. Comparison of potential range resolutions and potential resolutions of these signals speed are conducted. Dependence of the probing signals potential characteristics increasing the intra-frequency modulation degree is investigated.
Conclusions. Increasing the degree of frequency modulated does not result to a substantial increase in peak splitting cross-correlation function. Level pedestal signal grows and potential resolutions range of signals worsen with increasing degree of frequency modulated. Potential resolutions of signals speed are not changing increasing degree of frequency modulated.References
