Embodiment Construction

[0023] Below in conjunction with accompanying drawing, the present invention is described in more detail:

[0024] A general monopulse radar system consists of an antenna 1, a feeder network 3, a modulation amplifier 6, a circulator 7, a radio frequency receiving front end 8, a microwave receiving front end 9, a signal source 10, and a signal processing and system controller 11. Detection and system automatic calibration function, adding small signal coupler 2, digital control attenuator 4 and single-pole double-execution switch 5 in the system.

[0025] Such as figure 1 As shown, the system is a millimeter-wave radar system. The coupler 2 adopts waveguide coupling, and its coupling coefficient is -70dB. The power of the first signal 18 of 2 is 0dBm, the sensitivity of the system design is -130dBm, and the design of the coupler 2 and the digitally controlled attenuator 4 is reasonable. Considering that the maximum signal output by the modulation amplifier 6 is 50dBm, the iso...

Abstract

The invention discloses a monitoring structure and a method of a single pulse radar system automatic self-checking and a condition parameter. The structure comprises a coupler, a digital attenuator and a single-tool two-board switch. The structure is joined in the single pulse radar system. A radar transmitter signal is formed in a self-checking signal by the coupler and the radar transmitter signal is fed back in a radar receiving passage. The self-checking signal or a transmitter leakage signal is received by a receiver under the coordination between a receiving processing time sequence and processing algorithm of different models, thus the self-checking, calibration, delicacy automatic survey and transmitter condition detection of a radar system passage are achieved. According to the monitoring structure and the method of the single pulse radar system automatic self-checking and the condition parameter, any periphery testing equipment is not needed to be added, thus the monitoring and survey of the calibration and the condition parameter of the single pulse radar system are achieved. The monitoring structure and the method of the single pulse radar system automatic self-checking and the condition parameter can be applied to an online testing system of the radar system widely.

Description

technical field [0001] The invention belongs to the technical field of radar system design, and more precisely relates to a monopulse radar system self-inspection and monitoring structure and method of state parameters. Background technique [0002] Since radar system design requires integration and simplification of design, the measurement of system parameters and system self-test are often realized through manual access to signal sources. However, manual participation and the introduction of peripheral test equipment will not only bring cumbersome and complicated testing processes such as a large number of wiring connections, but also increase uncertain factors. There are problems such as rapid detection and accurate detection in the rapid response of system detection. Contents of the invention [0003] In view of the above technical problems, the present invention aims to provide a monopulse radar system self-inspection and state parameter monitoring structure and meth...
