Chirps in radar
WebJul 20, 2024 · We now can calculate the minimum number of chirps required to meet the velocity resolution: N= λ/ (2 * v*T’) Since the velocity is calculated by performing an FFT … WebWe propose a novel scheme of broadband LFM radar imaging system based on microwave photonic I/Q de-chirping. In the transmitter, a broadband linear frequency modulated signal is generated by photonic frequency-doubling. In the receiver, echoes reflected from the target are simultaneously sent to a couple of modulators in two polarization states.
