WebJun 11, 2024 · Chirp Radar is a type of radar that uses frequency modulation and pulse compression (which may confuse many as chirp has also been used as a synonym for “pulse compression”), which combines the capabilities of … When the Frequency-Time characteristic is non-linear, the Fourier integral is difficult to evaluate. In such cases, it is possible to resort to an approximation method such as the stationary phase approximation, or to use numerical methods. Often (as in radar applications) a(t) is a slowly varying function of time and th…

WebJun 23, 2024 · Slope-Shift Keying LoRa-Based Modulation Abstract: LoRa, a low-power long-range physical-layer communication method, is one of the emerging technologies in low-power wide-area networks (LPWANs). In LoRa, a linearly varying-frequency up chirp and its cyclic shifts act as an orthonormal basis set for message representation. WebOct 3, 2024 · The general expression for the basic chirp, ignoring the amplitude, phase and frequency, is written as x(t) = ej ( πμt2 + 2πft + θ) The factor π is actually 2π scaled by 1 / 2. This is included to normalize the chirp rate as the slope of the instantaneous frequency which is defined as the derivative of the argument.
