Adaptable emission airborne spiking sonar

A new spiking sonar based in the commercial 6500 module is presented in this work that, unlike the previous versions, is capable to vary both the duration and the frequency of its emission. This feature is provided by a PIC18F452 device that also controls the module integrator to generate the sequence of spikes whose density is proportional to the strength of the echo. The advantages of this adaptable emission are shown by analysing the system's behavior in some practical situations.
