What is LFM in RF?
A novel radio frequency (RF) steganography scheme is proposed to hide digital communication in linear frequency modulation (LFM) radar signals.
How do you calculate chirp time?
△R = C/(2 * B) Therefore, bandwidth can be easily calculated. Now that extended bandwidth can be calculated, the idle time is shown to be a function of the extended bandwidth. At this point, we have calculated the total chirp time that meets our requirements.
Why is a chirp signal used?
Chirp signals are useful when your system is nearly linear in the simulation range. They are also useful when you want to obtain a response quickly for a lot of frequency points. The frequency-response model that results when you use a chirp input contains only frequencies that fall within the range of the chirp.
What is chirp modulation?
Chirp modulation
This type of modulation employs sinusoidal waveforms whose instantaneous frequency increases or decreases linearly over time. These waveforms are commonly referred to as linear chirps or simply chirps. Hence the rate at which their frequency changes is called the chirp rate.
