radar return signal with a bit of a current waveform of the subfamily, and wherein the signal processing circuitry permutes the bit-shifted return signal and correlates the bit-shifted radar return signal with the current waveform of the selected subfamily to generate the enhanced detection output...
Here we use a GS-type algorithm to design an FM waveform jointly with a low-loss amplitude taper. The focus on FM structure is to ensure the waveform is amenable to a physical radar transmitter by avoiding phase discontinuities (per Section 1.3.1). The jointly designed amplitude taper then ...
As an example, a feature 144 within a cell 142 may be the signal-to-noise ratio (SNR) computed by a constant false alarm rate (CFAR) algorithm. However, it should be understood that other methods may be used to target and identify features 144 within a cell 142. One or more ...
In a modern SAR imaging system, a digital image formation algorithm generates and applies the required phase pattern. While the incoming SAR signal phase pattern is nominally quadratic in each coordinate, many variations and subtleties are present to challenge the IFP. For instance, the quadratic ...
CFAR –Range-Doppler detection algorithm is based on Constant false-alarm rate algorithm, cell averaging smallest of (CASO-CFAR) detection in range domain, plus CFAR-cell averaging (CACFAR) in Doppler domain detection, run on the range-Doppler power mapping to find detection points in range and...
7.3.4 Serializer Status and Monitoring The DS90UB635-Q1 features enhanced FPD-Link III diagnostics, system monitoring, and Built-In Self Test capabilities. The device monitors forward channel and back channel data for errors and reports them in the status registers. The device also supports ...
Since the displacement of vital signs, such as respiration and heartbeat, is very small, the phase-based range-tracking algorithm has a better result for obtaining accurate vital signs detection. If a Fourier transform is performed over each period of the IF signal (2–4), its associated rang...
