It is well known that the coherent effect occur when charged particles in a bunch radiate in phase. This is accompanied by a quadratic increase in the radiation intensity and significantly influences the radiation spectrum. The coherent radiation is characterized by a form factor, which is the coefficient mainly depending on the ratio of bunch dimensions to the observed radiation wave length. The form factors will be different for the synchrotron and transition radiation because of their different nature of radiation. Now electron accelerators that produced beams with a sub-picosecond bunch length and a picosecond distance between them already exist. Through the appearance of interference between radiation from such a sequence of bunches, the total intensity is no longer equal to the sum of radiation from each bunches. For this reason, it is essential to determine the form factor of an arbitrary electron bunch sequence. Herein the uniform bunch distribution will be the special case. In this report we describe an approach to obtaining the form factor of the arbitrary bunch sequence.
