Audio signal comparison from Radar

I an working on a student project. We have a radar that gives an audio detection using headphones to indicate the type of target. Target types are (eg car/truck/man). Radar distinguishes between these targets based on doppler variation, down converts this into audible range and operator can hear it through headphone. System has provided sample audio files corresponding to each type of target(man/car/truck) to train the operator to know as to what he is hearing when live signal is fed and accordingly decide what target it is.

I intend that a software can do the job of this operator.

I want to compare live audio signal input from Radar with 7 different test audio files and want the software to tell me which file matches the input.

kindly educate me .... can these audio fingerprinting softwares do my job.
