Chirp ramp time
WebThe paper presents a wideband, low-power chirp synthesizer for Ku-band FMCW radars. The DDS-driven ADPLL chirp synthesizer generates chirps up to 2GHz bandwidth. A low-power DDS is employed to generate a stepped reference frequency for ADPLL to ensure the long term chirp linearity, while the ADPLL fulfill the ramp-interpolating linearization by … WebAn apparatus comprises a frequency accumulator to produce a frequency ramp, and a symbol modulator to receive symbols and to add to the frequency ramp frequency offsets representative of the symbols, to produce a modulated frequency ramp for a modulated chirp. The apparatus includes a spreading factor controller to control a roll-over rate of …

WebFrame Idle time depends on the duty cycle you want while transmitting functional chirps. Duty cycle is a ratio of the Active Chirping time to the total frame time. Frame periodicity = [(chirp_ramp_time + chirp_idle_time) * (chirp_end_idx - chirp_start_idx + 1) * numOfLoop + idle_frame_time]. WebAbout Active frame time, for a chirp repetition time of 131.50us and 53 chirps, the minimum frame repetition time can be 6969.5us or 6.97 ms. The active frame time is 8.42ms as per the estimator. I assume that in …

WebMay 6, 2015 · A linear chirp or linearly swept sine is a signal in which the frequency changes linearly with time: the starting frequency changes into the ending frequency over time at a rate of: and is the amount of time it … Webthe time difference between the start of two consecutive chirps. This in turn depends on how fast the frequency sweep can be performed and the minimum inter-chirp time allowed. The faster the MMIC can ramp the frequency, the higher the maximum unambiguous velocity. TI’s MMIC allows a fast ramp of 100 MHz/µs.
