FMCW and pulse radar architectures are compared in this content. FMCW radars are easy and cheap to make, using separate antennas for transmitting and receiving. They are suitable for short-range applications like automotive radars. Pulse radars, on the other hand, are used for long-range applications like weather monitoring or aircraft detection. Pulse radars require fast ADCs and are more difficult to design than FMCW radars. The article discusses building a modern pulse radar with fast digital signal processing while keeping costs low. The system features block diagrams, simulations of ADC and DAC filters, and the use of FPGA for accurate timing and data management.
