Problems solved by technology
At present, most of the data acquisition systems used for PCs are based on the ISA bus, and its biggest disadvantage is that the transmission data speed is low and real-time transmission cannot be realized.
At the same time, the previous radar video real-time data acquisition schemes have problems such as data acquisition speed and signal processing effect distortion in hardware, drivers and software to varying degrees, and cannot be effectively promoted in terms of practicability and feasibility.
