WebApr 12, 2024 · Phased array beamforming has been used in radar and communication systems since the mid-20th century. In recent years, these systems have seen extensive adoption in areas such as 5G mobile communications, military and commercial radars, satellite communications, and automotive applications. A chirp is a signal in which the frequency increases (up-chirp) or decreases (down-chirp) with time. In some sources, the term chirp is used interchangeably with sweep signal. It is commonly applied to sonar, radar, and laser systems, and to other applications, such as in spread-spectrum communications (see chirp spread spectrum). This signal type is biologically inspired and occurs as a ph…
Web1 is a chirp, and 2 is the phase variation due to the stepped variety of the carrier frequency of the signal. Thus, the signal processing is implemented by the fol-lowing two steps: (1) the pulse compression of the chirp at each PRT gives the coarse range profiles; (2) the inverse dis-crete Fourier transform (IDFT) of the coarse range profile WebApr 12, 2024 · Comparing the calculated and measured values from Table 2 and Table 3 while keeping in mind that the measurement step of the oscilloscope was between 0.1 µs and 0.4 µs depending on the oscilloscope ...
