Drive a 1KW Marine Transducer

[zizouth]

I would like to make a circuit, an interface, to drive a 1KW Airmar marine transducer then process signal to an PC.

The communication part with the PC ok, I can put an STM32 and process the signals via ADC converter. The problem is how to send the 1KW to the transducer and get the echo. I couldn't find any documentation on this part. Any ideas?

A development module exists but at more than 3000$ it is out of budget for me

Have you tried Googling for "echo-sounder circuit"? It might be possible to beef up an existing circuit to handle 1kW.

Some old magazines had echo sounder schematics/designs that could easily be rehashed/updated..

Here's one I found in 'seconds'... http://n5dux.com/ham/files/pdf/Down-Under Depth Sounder.pdf

Years searching with transducer circuits , piezoelectric circuit etc. But never with echo-sounder words.
I found tons of circuits thanks a lot
