Abstract
In the past years, bistatic Radar Cross Section (RCS) characteristic has been caught increasing attention. The paper presents a bistatic RCS measurement system of full-size goals, which uses photoelectric conversion technology to solve the problem that excessive electrical signal attenuation exits because of the large distance between sending and receiving antenna. The paper analyzes the basic principle of photoelectric conversion and RCS measurement system, applies photoelectric conversion technology to RCS measurement system, and tests whether RCS measurement system works well while using photoelectric conversion technology. The test results show that the system can efficiently obtain the bistatic RCS characteristic of full-size targets.

Summary
The main purpose of stealth technology is to reduce the Radar Cross Section of target. RCS measurement can be divided into Near-field, Outdoor-field measurement, as well as single and double station measurement. Near-field measurement as an advanced measurement technology has been widely used in radiation scattering measurements and radar target imaging. Compared with the Near-field measurement, the main features of Outdoor-field measurement are: size of the object can be within a wide range; the measurement results are closer to the real situation of the target; Far-field measurement condition is easy to satisfy, and can be directly used for the acceptance of products’ electromagnetic scattering properties [2]. Compared to traditional single-station RCS measurements, bistatic RCS measurement can simulate multi-base anti-stealth system to measure the measured target stealth performance at different pitch angle, which reflects the targets’ actual stealth performance. The bistatic RCS measurement systems have sprung up in recent years, which have been applied in the Near field and Outdoor games, and developed rapidly. The bistatic RCS anti-stealth is applied to an increasing number of occasions, for example, 52E6MU Struna-1MU/Barrier E (NNIIRT, Russia) is the proposed multistatic system that can detect against low RCS targets [6]
