Hi, currently I'm doing project based on bio-inspired signal as new source waveform for radar application. However, I faced difficulty on detection. Typical time domain correlation/match filter method seem doesn't work with my signal. Is there any better other option on how I can do my detection? Kindly please advise.
Below are some properties of my signal that I'm working with:-
1. Very short (less than 3ms)
2. Signal pattern have its own unique properties (each signal contain unique frequency component, and can be found on both Transmit and Echo signal).
3. Wideband signal.
Before that, I have try pitch detection technique and it seem there is acceptable result. But, I'm just not very sure the appropriate method on how to correlate between Tx and Echo signal since I'm quiet new in signal processing field. If somebody can advised me on how to perform correlation in frequency domain with basic matlab code/algorithm, it will be very good.
Thanks in advances.
Dear Nur,
I'm not familiar with your problem.
But, there is a waveform that is very useful in the animal world and in sophisticated radar systems. This is the Linear FM signal (in the frequency domain) - also known as the Chirp Signal (in the time domain).
You might want to read up on it.
As I recall, it is used by dolphins and bats, and is used in high resolution sonar and radar systems.
Even if it does not apply to your specific problem, it is very interesting.
Good luck!

I work on the studies of stochastic resonance which is able to utilize noise to detect weak signals and moreover is suitable to short data sets.
Thanks to all for your feedback. I really appreciated it.
Btw to Dear Zijian Qiao, your works area seem identical with my work (short data set, weak signal waveform). Do you have detail manuscript/ paper that I can refer to.
Thanks
