RF Transceiver Integrated Radar Signal Preprocessing Method Based on Dual Chip B9361

Target detection, location, tracking, imaging and identification are achieved by utilizing the reflection or scattering of electromagnetic waves by the target^[1]. Whether in military or civilian fields, radar is deeply integrated into all aspects of production and life. The RF transceiver system is an important component of radar. Traditional radar systems adopt a discrete single-machine design, which has a heavy hardware proportion, a narrow adjustable range, high system upgrade difficulty, and high cost, as well as large volume, which is not conducive to system construction and debugging. Miniaturization, wide frequency band, and high integration have become the development trends of radar. This paper introduces a radar signal preprocessing method based on dual B9361 chips, verifying the necessity of adopting the dual B9361 architecture in the field of radar short-range detection. The transmission control and reception control of B9361 are elaborated in detail, and the transmission and reception verification is carried out using typical signals as models. To expand the functions and performance of radar, the range migration module and coherent accumulation module are inserted into the signal processing flow, laying a good foundation for subsequent improvement of radar system indicators.
