Abstract: PURPOSE:To enable a simple-constitution circuit to shorten an arithmetic time and attain high multiplication as to a Fourier integral system using a signal detection  system, by previously storing sine integral Xs and cosine integral Xc constituting a formula in a memory unit, and then by reading the both at need. CONSTITUTION:A signal detection system consists of cumulative adders 5 and 7, series-parallel converter circuits 31 and 33, OR circuits 32 and 34, memory unit 35, etc. In this constitution, when sine component Xs of digital input signal y(t) is calculated by comulative adder 5 while its consine component Xc is also calculated by cumulative adder 7, Xs and Xc are converted in parallel by converter circuits 31 and 33 and inputted to OR circuits 32 and 34. Next, access is attained by using their outputs as addresses, of memory unit 35 so that the existence of a signal can be found. This signal detection system attains only access to the memory unit with no calculation as to values of Xs and Xc, thereby shortening the processing time for signal detection.

Abstract: PURPOSE:To obtain radio wave anti-jamming capacity having high reliability, by judging the presence of a jamming radio wave corresponding to the relative distance between a target and a projectile and determining the tracking possibility to a jamming source with the cyclicity of the jamming radio wave taken in consideration. CONSTITUTION:The power intensity of a target signal received is detected by a detector 12 while the intensity of receiving power to be received from a target inherently is calculated from the capacity of a radar apparatus itself on the basis of the distance signal from a distance tracking circuit 11. This calculated value is compared with the output of the detector 12 and the cyclicity of a jamming radio wave is detected and, when both of them coincide, the operation of the radar apparatus is set to a jamming source tracking mode. Therefore, erroneous operation due to the size of the target or circumferential environment is prevented.
