The invention discloses a receiver of a radar simulator, comprising a first down-conversion system, a second down-conversion system, a detection system, and a frequency storage system, wherein a target radar signal is used as a first radio frequency input signal, and the first down-conversion system According to the first radio frequency input signal, a detection input signal is provided to the detection system, and a second radio frequency input signal is provided to the second down-conversion system; the detection system provides the first digital signal to the frequency storage system according to the detection input signal; the second down-conversion system is based on The second radio frequency input signal provides a second digital signal to the frequency storage system; the frequency storage system provides a second local oscillator input signal to the second down-conversion system according to the first digital signal to the second down-conversion system, and according to the first digital signal The signal and the second digital signal generate a radar analog signal. The receiver of the radar simulator reduces the cost and design difficulty, and improves the research and development speed.
Description
technical field [0001] The invention relates to the technical field of radar testing, in particular to a receiver of a radar simulator. Background technique [0002] Radar simulator is a tool used to test radar performance and reduce the cost of radar experiments. Common radar simulators forward the signal by copying the target radar, and simulate virtual targets on the radar screen to achieve the effect of target radar deception. , This technology has a very wide range of applications in military and civilian radar testing, radar electronic countermeasures, radar operation training and other occasions. [0003] In the design process of the radar simulator, in order to achieve a complete simulation of the target radar signal, it is usually necessary to down-convert the signal emitted by the target radar and perform a complete "copy". This approach is easier to achieve when the radar bandwidth is not high. For example, the target radar is a 10GHz-10.2GHz chirp radar with a b...
