WebRadar Blind Speed Calculator. This CalcTown calculator calculates the radar blind speed according to the blind speed equation. If the Doppler frequency produced by a moving target is exactly the same as PRF, then sampling occurs at the same point in each cycle. The blind speed is a radial speed of the airplane at which the phase shifting of the ... WebFrequency-dependent I/Q imbalance and frequency-independent I/Q imbalance are the major impairments in wideband zero-IF receivers, and they both cannot be ignored. In this paper, a blind calibration model is designed for compensating these I/Q imbalances. In order to accurately estimate the imbalance parameters with low cost, a classification rule …

WebNov 4, 2013 · Lock-in thermography is increasingly becoming popular as a non-destructive testing technique for defect detection in composite materials for its low heating excitation. … Webfrequency. However, we estimate the signal bandwidth and carrier frequency from the bandpass signal inspired by a blind process discussed in [33]. A baseband signal is achieved by down-converting the received bandpass signal [34]. The baseband received OQPSK signal with unknown tim-ing and frequency offsets can be expressed in … WebJul 17, 2006 · In this paper, we address the problem of blind carrier frequency offset (CFO) estimation in orthogonal frequency-division multiplexing (OFDM) systems in the case of … food lumberton nj
