Minimal SNR to distinguish LFM target from noise at range doppler output

There's a few problems with your code but you're essentially there. I haven't had the chance to do a deep-dive into your code, but I few changes gets you where you want to be. First, you're definitely ...

Minimal SNR to distinguish LFM target from noise at range doppler output

The primary point causing Just Noise is that you have fc=10e9 and fs=1e9 Heavy Undersampling. Basically you don't have signal. ...

Minimal SNR to distinguish LFM target from noise at range doppler output

I'm not sure you're going to get good detection performance for your example at only 10 dB signal-to-noise ratio (SNR). Detection, in general, is a tradeoff between achieving a high probability of ...

Calculating SNR of one N-point DFT over another M-point DFT in frequency domain

The power level of each bin in the power within the resolution BW of the DFT (think of each bin as the average power within the bandwidth of a bandpass filter centered on each bin, which is what the ...

Typically signal to noise ratio is quoted over a time average. Remember that \begin{align} \textbf{u}(n) \end{align} is additive white noise. This means that the values $\textbf{u}(n)$ are random ...
