What is chirp bandwidth?
The chirp bandwidth can be straightforwardly computed as the product of βr times the duration of the pulse, i.e., the chirp rate can be expressed as. (5.74) where Br is the transmitted bandwidth and Tp is the duration of the pulse. A linear instantaneous frequency results in a quadratic phase, i.e., (5.75) π π
What is LFM chirp?
LFM Chirp Waveform. The linear chirp signal, or LFM signal, is widely used in sonar and radar systems [20]. A linear chirp is a sig- nal, in which the frequency linearly increases (up-chirp) or decreases (down-chirp) with time.
What is a chirp frequency?
What is frequency chirp? A chirp is a signal in which the frequency increases or decreases with time. This picture shows a linear chirp waveform; a sinusoidal wave that increases in frequency linearly over time.
What is lfm in radar?
In modern radar and communication systems, Linear Frequency Modulation (LFM) signal is a kind of typical non- stationary signal. It is important to recognition and estimate the parameter of LFM signal fast and precisely for radar electronic reconnaissance and resistance system.
