In fact, since the PSLR is related to how much the waveform is equal to itself, the number of independent samples (with their phases) represents the degree of freedom available to make the correlation ...
Historically, the design of chirp radar in the Western was made public in the 1960s [16] and, in the Eastern world, in the works (1950s) by Yakov Shirman [17] , who received the IEEE Pioneer Award in 2009 ...
Gabriele Pavan contributed to the HNLFM analysis and gave the Matlab software support together with Francesco De Palo who also contributed to the Noise Radar and signals generation. ...

Following recent results, we show that random-FM excitations retain many advantages of chirps and provide the ability to frequency-shape the excitations matching the transducers features. ...
Here, we propose a system based on random-FM excitations, capable of enabling MIMO with minimal changes with respect to a chirp-based setup. ...
In the middle plots, the spectrum profiles that would be obtained by a linear chirp are superimposed in gray for reference, i.e., the characteristic spectrum of the two-probe system. ...
