Abstract :
A kind of convenient, low cost and portable marine radar image acquisition method which is based on embedded system is introduced. The system, which could automatically gather radar signal, is consist of CPLD, ARM microprocessor, ADC and amplifier. Radar echo video, heading position, bearing and trigger pulse signal are sent to the control unit through filter and acquisition circuit. For realizing remote transmission and storing, radar image is compressed based on wavelet processing method.
