Complementery and barker code

I want to study about complementary code and barker code used in radar application. If you have any example code please share.

You can certainly do complementary codes. There are a few things you have to keep in mind when implementing them. You may know this already but I'll put it here for anyone reading the post.

You need multiple phase-coded waveforms which you will combine after. If you are using the radarTransceiver object, then you will have to change your waveform and matched filter between each pulse. Then after you finish your frame/dwell, you can add the pairs of pulses together and continue your processing steps for your application.

Here is a radar example for using PhaseCodedWaveform.

One of the options in the PhaseCodedWaveform is barker.

HTH

for barker , Generate the signal w.r.t to phase. consider if condition 0 degs as 0 value and 1 deg as 1 value. In that phase coded waveform they will mention number of chips, consider below 13 length(refer Radar system analysis and design using Matlab by mahafza). based on the length using if condition generate waveform. correlate/matchfiltered/convolute with same function. acoording to the length, u will get the PSL of 20*log10(length).
