the invention concerns a short range radar system with short range radar sensormitteln, means 41 for rf impulserzeugung for sensormittel, characterised by the fact that the means for rf impulserzeugung to supply pulses with adjustable pulse duration (51, 53) are trained.STEINBUCH DIRK...
This example shows the effects of pulse compression, where a transmitted pulse is modulated and correlated with the received signal. Pulse compression is used in radar and sonar systems to improve signal-to-noise ratio (SNR) and range resolution by shortening the duration of echoes....
It also means there is less droop over the pulse width because the PA’s temperature changes less over the duration of the pulse. This can be seen in Figure 7 and Table 2. GaN devices generate a lot of output power. Although efficiency in GaN is relatively hi...
A short duration pulse is likely to be detected and mapped into only one or two range bins, rather than being spread over many bins. However, a longer pulse duration or width allows for a greater amount of signal energy to be transmitted and a longer time for the receiver to integrate ...
The RF waveform of the combined main and secondary pulses is shown in Fig. 2. The larger trace is the original chirp and the smaller delayed trace is the secondary copy which is delayed. In this case the delay time is equal to almost half of the pulse duration time. ...
The pulse duration is called the “pulse length”, and is measured in micro-seconds. The pulse length is usually called Pulse Width in radar systems. These listening times represent one pulsed radar cycle time, normally called the interpulse period or (IPP) or pulse repetition interval (PRI)...
