The working principle is as follows: processing the signals by waveform generation and up-conversion to generate transmitting signals of required frequency bands; the wide-narrow band receiving module carries out filtering amplification and frequency conversion on the signals from the receiving antenna after low-noise amplification, and the signals after frequency conversion are sent to the acquisition module for digital processing; the frequency comprehensive source provides a local oscillator signal with high stability, a sampling clock signal and various reference signals for the system; the acquisition module is used for digitally receiving and digitally down-converting the signals; all power supply, control and radio frequency signal connections among the modules are connected through the multilayer microstrip board.

The local oscillator and the clock signal realize multi-path power division internally: in order to reduce the volume and improve the reliability, the local oscillator and clock signal design realizes multi-path power division inside. The design realizes power division through a strip line, and is realized by adopting a strip line Wilkinson circuit. The connectors on the modules are connected with the connectors on the back plate in a blind matching connection mode, enter the multilayer micro-strip plate and are transmitted in a strip line mode, and radio frequency signals are vertically transited to corresponding interfaces through insulators. And by means of similar structural design and circuit design, the local oscillator signals are subjected to power division, and channel expansion is achieved.
Electromagnetic compatibility design: in the back plate, various signals pass through and possibly interfere with each other, so that the electromagnetic compatibility design is very important, radio frequency signals with different frequencies need to be isolated, and the radio frequency signals and low-frequency signals need to be isolated. Power and control are susceptible to interference, affecting the performance of the system. In the design, the power supply is designed to be a layer independently, the layout wiring is possibly close to the ground, the loop area of differential mode radiation is reduced, and the interference is reduced.

The design is designed according to the frequency difference, and a single layer or a plurality of layers are taken in the design of the multi-layer back plate, and an analog ground is used.
In the design of the multilayer microstrip board, the problem of dielectric loss needs to be fully considered, and the amplitude of local oscillator and clock signals needs to be reasonably designed so as to avoid the problem of insufficient amplitude caused by the dielectric loss of the board.
The broadband and narrowband receiving module outputs a plurality of signals to the waveform acquisition module. The narrow-band signal has a plurality of channels, and the isolation design between the channels is very important. The requirements are met by the isolation of a large-area ground and the isolation of the ground arranged between layers.
The broadband signal passes through the analog demodulation circuit to obtain an I path signal and a Q path signal, strict equal-amplitude and equal-phase design is required in the transmission process, and equal path length is strictly achieved in the design.
During the design of the multilayer board, simulation design is carried out by modeling HFSS software of Ansoft corporation, and signals are optimally designed for internal transmission.
Fig. 5-8 are simulation results of output metrics of the system, where S11 refers to the reflection coefficient of the 1 port, the 1 port is the input port, S22 refers to the reflection coefficient of the 2 port, and the 2 port signal is a signal divided from the 1 port; s33 indicates the reflection coefficient of the 3-port, and the 3-port signal is a signal divided from the 1-port; s21 indicates the transmission coefficient from port 1 to port 2, which indicates the degree of loss due to signal transmission; s31 indicates the transmission coefficient from port 1 to port 3, which indicates the degree of loss due to signal transmission; s23 indicates the isolation between 2-port and 3-port, and the isolation indicates the degree of interaction between port signals.
