PURPOSE:To enable the generation and inputting of a simulated target signal even if transmission is performed in a cycle shorter than the sample transmission cycle of a radar because of clutter suppression, by correcting the indicated distance of a distance indicating switch to the distance within the transmission cycle thereof. CONSTITUTION:The indicated value by the distance indicating switch 36 of a simulated target signal generator 34 is corrected by a distance correcting circuit 37 so as to correspond to the short section of the repeated cycle of a transmission trigger and either one of distances due to the switch 36 and a circuit 37 is selected through a change-over circuit 39 corresponding to the cycle of the trigger signal of a radar apparatus 33 and, when coincided with the distance signal from the apparatus 33, a coincidence signal is outputted from a distance coincidence circuit 40. Similar azimuth coincidence output and the indicated number from a high number indicator 41 are also applied to output a trigger output from a simulated signal trigger generator 42 and a high frequency signal having pulse amplitude same to transmission pulse amplitude is outputted as a simulated target signal from a signal converter 43. By this constitution, the simulated target signal is generated and inputted even if transmission is performed at a cycle shorter than base frequency because of clutter suppression. |
