In order to help understanding of the present invention, the related art 1 will be described with reference to FIGS. In FIG. 1, 1 is a tracking radio wave (frequency is assumed to be F1), 11 is a receiving antenna, 12 is a receiving unit, 13 is a signal processing unit, and 14 is a reflective payload having a plurality of types of electrical specifications. This is a payload storage that stores one type or a plurality of types of reflection type payloads specified in accordance with a control command and selectively injects them into the space. Reference numeral 21 denotes a reflective payload emitted into the space. FIG. 2 is an explanatory diagram of the payload storage 14 and categorizes reflective payloads having strong reflection characteristics at frequencies F1, F2, F3,... Into storage locations A, B, C, D,. When a reflection payload having an optimum electrical specification is designated by the analysis result of the tracking radio wave 1 by the signal processing unit 13, the corresponding reflection payload is emitted toward the space.
[0009]
Next, the operation will be described. When the tracking radio wave 1 is received, the signal processing unit 13 analyzes tracking information such as the frequency of the tracking radio wave 1. If the frequency of the tracking radio wave 1 is F1, a reflective payload 21 having a reflection characteristic strong with respect to the frequency F1 is designated, and the corresponding reflective payload 21 is emitted from the payload storage 14 toward the air. The emitted reflective payload 21 floats and stays in the air, reflects the tracking radio wave, and obstructs the location of the mother body. In this way, since the reflective payload 21 having a strong reflection characteristic with respect to the frequency of the tracking radio wave at that time can be selected and used, the interference effect on the tracking radio wave can be enhanced.
