Example Embodiment
[0040] Example 1
[0041]Figure 1 shows a block diagram of a wideband radar system using multiple transmitters and multiple receivers. The radar system of this embodiment is mainly composed of a transmitting / receiving array antenna, a transmitter sub-system, a receiver sub-system, a clock source, a monitoring sub-system, and a power supply. The transmitter sub-system of this embodiment includes M parallel sub-transmitters, which generate M channels of frequency division signals. The receiver sub-system includes N parallel sub-receivers and signal processors, and the sub-receivers are M channels. Frequency division parallel receiver. The components of the radar system of this embodiment are described as follows:
[0042] ①Transmitting / receiving array antenna: The receiving antenna and the transmitting antenna can share a set of array antennas. At this time, as shown by the dotted line in Figure 1, each extension of the receiver and each extension of the transmitter are connected to...
