Description

Technical Field

[0001] The invention belongs to the technical field of signal processing, and in particular relates to an analog signal source system with replaceable components. Background Art

[0002] Anti-radiation equipment uses the electromagnetic signal emitted by the electromagnetic radiation source as the control signal, flies to and destroys the electromagnetic radiation source through certain control rules, and is an important and indispensable equipment in the current electronic information field to obtain electromagnetic dominance and suppress the opponent's system. Therefore, the importance of anti-radiation equipment is growing. In the later stage of the development of anti-radiation equipment, in order to fully verify the functions and performance of the actual application of the product, multiple field target tests are required. However, the target system currently used to examine the overall performance of anti-radiation equipment is expensive. If the development unit hits the target and damages the core components of the system in one test, subsequent tests will require the purchase of related components and wait for the target system to be repaired and improved. In the long run, not only will the overall test cycle be greatly extended, but it will also cost a lot to purchase and guarantee the target system. Therefore, designing an analog signal source target system with replaceable components has great practical application value. Summary of the invention

[0003] Purpose of the invention: To design an analog signal source target system with replaceable components, which is mainly composed of an analog signal source, a power amplifier, an antenna, a waveguide, a bracket, a control console, a power supply device, etc. In the system, the higher-value signal source and power amplifier modules are arranged in partitions with the relatively economical antenna modules and connected by waveguides. The signal source and the power amplifier module are protected secondary by stacking sandbags and other shelters, and the waveguide length can be comprehensively considered based on the transmission loss and the output power of the power amplifier module. In this way, the equipment that may be damaged in the test is the antenna or waveguide module, while the higher-value signal source and power amplifier modules can be effectively protected. Only multiple sets of relatively economical antenna and waveguide modules need to be backed up, and the target system can quickly respond to multiple test task requirements. It can be seen that designing an analog signal source target system with replaceable components can greatly reduce the time and capital investment in the construction of the target system, and save considerable time and economic costs for the comprehensive verification of the functions of the anti-radiation equipment.

[0009] Furthermore, the computer and the signal source are connected via an RS422 to USB cable for host computer control; the signal source and the power amplifier device are connected via an ultra-low loss cable and a corresponding circular connector. The ultra-low loss cable is used for signal output of the signal source, and the circular connector is used to power and control the power amplifier device; the power amplifier end and the antenna end are respectively connected to the soft waveguide, and then a certain number of hard waveguides are used to separate the two.
