Abstract

Analog-to-digital converters (ADCs) that convert analog signals into digital ones play a significant role in radar systems. The accuracy and resolution of radar readings are significantly influenced by the quality and performance of ADCs. This paper discusses and compares the application of five different types of ADCs in radar systems. It also elaborates on each ADC's working principle, advantages, and limitations. The parameters compared are resolution and dynamic range, signal-to-noise ratio (SNR), latency and sampling rate, power consumption, size, and cost. After thorough research, we concluded that each ADC differs depending on the designer’s desired application. For example, flash ADCs are the best when it comes to high-speed and high-resolution responses, which are critical for accurate measurements. However, we can conclude that the best among the compared ADCs for radar application would be sigma-delta ADC, which is better because it is inexpensive and has a high-resolution and dynamic range for radar operations.
