New and increasing threats abroad require long-range visibility and corresponding wide radar pulse
widths and long pulse repetition intervals, while the increase in urban warfare demands narrow radar pulse
widths and high pulse repetition frequencies to detect small, close threats."
The signal processing method for extracting biometric information from the radar signal reflected from the human body is dependent on the radar pulse
The radar pulse
width is 100 [micro]s and the PRI is 1 KHz.
The radar then measures the time difference between the transmission and reception of the radar pulse
and its echo to determine the position of the aircraft, and the frequency change between the transmitted pulse and its echo to determine the aircraft's speed.
The feasibility of this signaling as a radar pulse
compression is studied and some codes for CE-OFDM radar signals with favorable autocorrelation functions are also introduced.
The basic principle of UWB radar is to transmit electromagnetic (EM) radar pulse
to image the subsurface.
Integer values of a radar pulse
after the intermittent sampling are generated as
Binary codes with low autocorrelation sidelobe levels and high Discriminating factors are useful for radar pulse
compression , channel estimation, and spread spectrum communication applications.
Ambiguity function of radar pulse
[chi]([tau], f) is used for estimation of range- and Doppler resolution of radar .
