Abstract :
In order to achieve high-speed beamforming, a four-channel radar signal was extracted and converted from an analog signal to a digital signal. A dual-port RAM was implemented to obtain a continuous data transfer to the local computer hard disk with a speed of 10 Mbytes per second. Analog to Digital Conversion (ADC) that has 20 MHz of speed and 10-bit resolution was designed and tested; this ADC needs only one stage of Intermediate Frequency (IF) amplification. A Printed Circuit Board (PCB) was implemented as well
