  • Radar technology was originally used for military purposes to detect aircraft, missiles, vehicles, ships and other targets. With the development of technology and the evolution of society, radar is increasingly used in civilian scenarios. A typical application is that weather radar measures the echoes of meteorological targets such as clouds and rain to determine the location, intensity and other information about clouds and rain for weather forecasting. Furthermore, with the vigorous development of the electronic information industry, Internet of Things, communication technology, etc., radar technology has begun to enter people's daily life applications, greatly improving the convenience and safety of work and life. For example, automotive radar provides early warning information for vehicle driving by measuring the distance and relative speed between vehicles, between vehicles and surrounding objects, and between vehicles and pedestrians, which greatly improves the safety level of road traffic.
  • radar is classified in many ways. According to the positional relationship between radar transceiver sites, it can be divided into: single-station radar and dual-station radar.
  • single-station radar the signal transmitter and receiver are integrated and share an antenna; the advantage is that the target echo signal and the local oscillator of the receiver are naturally coherent, and signal processing is more convenient; the disadvantage is that signal transmission and reception cannot be performed at the same time, and can only be Signal waveforms with a certain duty cycle lead to blind spots in detection, which require complex algorithms to compensate; or signals can be sent and received at the same time, with strict isolation between sending and receiving, but this is difficult to achieve for high-power military radars.
  • the signal transmitter and receiver are located at different locations; the advantage is that signal transmission and reception can be carried out simultaneously, and continuous wave waveforms can be used for detection; the disadvantage is that it is difficult to achieve the same frequency and coherence between the receiver and transmitter, and the signal The processing is more complicated.
  • radar technology can adopt single-station radar mode or dual-station radar mode.
  • the transmitting and receiving signals share the same antenna, and the receiving signals and the transmitting signals enter different channels through the circulator.
  • RF processing link in this mode, continuous wave signal waveforms can be used to achieve detection without blind zones, provided that the receiving signal and the transmitting signal need to be well isolated, usually around 100dB of isolation is required to eliminate the impact of leakage of the transmit signal. Flooding of received signal. Since the single-station radar receiver has all the information of the transmitted signal, it can perform signal processing through matched filtering (pulse compression) to obtain higher signal processing gain.
  • the dual-station radar mode there is no isolation problem of sending and receiving signals, which greatly simplifies the complexity of the hardware. Since radar signal processing is based on known information, in 5G NR synaesthetic integration applications, known information such as synchronization signals and reference signals can be used for radar signal processing. However, due to the periodicity of synchronization signals, reference signals, etc., the blur diagram of the signal waveform is no longer a pushpin shape, but a nail plate shape. The degree of delay and Doppler ambiguity will increase, and the gain of the main lobe will be relatively small. The single-station radar mode is much slower, reducing the range of distance and speed measurements. Through appropriate parameter set design, the measurement range of distance and speed can meet the measurement needs of common targets such as cars and pedestrians. In addition, the measurement accuracy of dual-station radar is related to the position of the transceiver station relative to the target. It is necessary to select an appropriate transceiver station pair to improve detection performance.
