Problems solved by technology

[0008] Low-speed, single-function AD and DA chips can only meet specific requirements, but cannot meet the requirements of modern radar systems for large instantaneous bandwidth, real-time signal reception, large dynamic range, high sensitivity, and frequency resolution. Low-end AD and DA chips can no longer meet the requirements of modern radar systems. Radar Digital System Requirements

Abstract

The invention discloses a radar signal transmitting and receiving system and method with the function of supporting multiple waveforms. The system comprises an FPGA module and a DSP module. The FPGA module includes a waveform sending module, an echo receiving module and a chip configuration module. The system and method have characteristics of flexible control, high expansibility and high adaptability; the anti-interference performance of the system is enhanced by dynamic switching between waveforms; and requirements of fast tracking and recognition of moving targets are met.

Description

technical field [0001] The invention belongs to the technical field of radar signal transmission and reception, and in particular relates to a radar signal transmission and reception system and method supporting multiple waveforms. Background technique [0002] The radar detects the target by receiving the characteristics of the echo signal, and extracts the useful information of the target, such as distance, angle, speed of movement, target shape and nature, etc. With the development of digital technology, the radar system is rapidly developing in the direction of digitization, softwareization and modularization, and its application range is becoming wider and wider. [0003] The main task of radar waveform design is to select the appropriate signal for a given target environment according to tactical requirements, and to set the signal type and related parameters. Therefore, the research on radar waveform optimization design algorithm has become the most important part of ...
