What is the radar equation?
The radar equation describes the physical power budget of a signal emitted by the radar from the moment it enters the transmitter antenna until it is received by the receiver antenna. At the beginning, the transmitted signal is generated by the radar emitter chain.
What is radar theory?
The basic principle behind radar is simple - extremely short bursts of radio energy (traveling at the speed of light) are transmitted, reflected off a target and then returned as an echo. Radar makes use of a phenomenon we have all observed, that of the ECHO PRINCIPLE.
What is SNR in radar?
The 'Signal-to-Noise' ratio or, SNR (in short), is a metric that describes the signal performance in the presence of wireless channel noise (interference). In the linear scale, the SNR is the ratio of the signal power to the noise power. The wireless channel is never noise-free.
