<p>PURPOSE:To enable a display device and a signal processor for a primary radar to be used even when a secondary radar is used by adding a radar data transmitter to a radar device where the primary and secondary radars are provided successively. CONSTITUTION:The radar device is provided with the primary radar (PSR) 1 and secondary radar (SSR) 2 successively. The trigger generation control circuit 4 of a radar data transmitting device 25 generates a trigger for performing transmission and reception by both radars 1 and 2 at different repetitive periods. Further, a storage device 5 is stored with a received signal of at least one cycle of the repetitive cycles of the SSR 2 and a clock generating circuit 6 varies the writing and reading reception speed of the storage device 5 to compress the received signal of the SSR 2 with time. Then, a SSR data interpolating circuit 7 interpolates the received signal of the SSR 2 read out of the storage device 5 based on the trigger synchronized with both the PSR 1 and SSR 2 and also outputs radar data to the signal processor 8 of the PSR 1.</p> |
