In existing literature, no detailed analysis has ever been performed that combines analysis of 192 Radar Signal Analysis and Processing Using MATLAB 5.2.2. LFM Ambiguity Function Consider the LFM complex envelope signal defined by (5.16) In order to compute the ambiguity function for the LFM complex envelope, we will first consider the case when . In this case the integration limits are from to . Substituting Eq. (5.16) into Eq. (5.1 Ambiguity Function of FMCW waveform.

Matched filtering, ambiguity function, spectrogram, range transforms. Matched filtering increases the SNR of signals and improves detection performance.

The maximum value of the normalized ambiguity function is one. The zero Doppler cut of the ambiguity function depicts the matched filter response of a target when the target is stationary. From the plot, one can see that the first null response appears at 10 microseconds, which means that this waveform could resolve two targets that are at least 10 microseconds, or 1.5 km apart. Matched Filtering and Ambiguity Function.

The ambiguity function is defined by the complex envelope of the signal. The normalized ambiguity function is where Ex is the squared norm of the signal, x (t), t is the time delay, and fd is the Doppler shift. The asterisk (*) denotes the complex conjugate. The ambiguity function describes the effects of time delays and Doppler shifts on the output of a matched filter.

You shouldn't rule it out. Also, your signals would look more alike if you removed the  Appendix 3A: MATLAB Code for Plotting Ambiguity. Functions.

For small Doppler shift , the delay location of the peak response is shifted from true delay by: Preferred in situations with ambiguous Doppler shifts. This MATLAB function returns the magnitude of the normalized periodic ambiguity function (PAF) for one period of the periodic signal X. The ambiguity function describes the effects of time delays and Doppler shifts on the output of a matched filter. The magnitude of the ambiguity function achieves maximum value at (0,0).
