Our proprietary dedicated shape radiolocation reflectors warranted creation of novel types of devices for their dispersal that allowed to form clouds of the reflectors both in upper and lower atmosphere. Here we present the characteristics of only some of the kinds of the dispensers of dedicated shape reflectors.
1. Mechanical dispenser
General view of the mechanical dispenser of the dedicated shape radiolocation reflectors is given in Fig. 1.

This device is represented as a set of 10 cassettes (1) made in the form of drums which are fixed rigidly on the rotating axis. The axis with the cassettes begins to revolve from the motor to which it is connected using an adapter (2). Besides a coupling sleeve, there is a PCB (4) placed on it for electronic control over operation of the device.
Each of the revolving cassettes is divided into compartments covered with lids to keep in place the reflectors contained in them.
General view of one such cassette filled with reflectors that are placed into compartments with the lids on is given in Fig. 2.

The dispenser has the following main characteristics:
| Limiting revolution rate of dispenser shaft | 2500 rev/min |
| Maximum length | 1221 mm |
| Maximum diameter | 217 mm |
| Number of cassettes (drums) | 10 |
| Weight of dispenser without reflectors, not more than | 40 kg |
| Weight of dispenser with reflectors, not more than | 65 kg |
| Maximum number of reflectors placed in one cassette | 25,000 |
| Maximum number of dispersible reflectors | 250,000 |
| Maximum ESR value from reflector cloud after opening 10 cassettes | 17 dBм2 |
| Voltage supply of cassette opening control device | 6-6.5 V |
| Current consumed by cassette opening control device, not exceeding: In waiting mode During opening of cassettes |
0.01 А 10 А |
| Parameters of external control signal for cassette opening: Pulse amplitude (at Rн > 560 Ohm) Pulse width Pulse train period, not less than Polarity |
4.5-6.5 V 10-100 ms 8 s Positive relative to total negative of power supply |
Note that this proprietary device can be outfitted with radiolocation reflectors designed to work in different bandwidths. Besides, also feasible are different modes of dispersal (single and in-sequence) brought about during motion of the device following the trajectory assigned.
2. Dispenser of dedicated shape radiolocation reflectors employing gas jets
Since the majority of our proprietary types of dedicated shape radiolocation reflectors have very good aerodynamic characteristics, their dispersal calls for employment of high-speed gas jets formed during incineration of some chemical substances.
General view of such a dispenser for these radiolocation reflectors is given in Fig. 3.

The device consists of a body (1) filled with reflectors and a gas jet production compartment (2). A remote operation control is installed in the body, the body itself being divided into two parts which, depending on functional assignment of the system, can be filled up with reflectors designed for operation either in one, or in two frequency ranges.
Main characteristics of the device:
| Total number of reflectors | 86,000 |
| Operating frequency range of reflectors | 8.5–10.5 GHz |
| Weight of empty dispenser | 46 kg |
| Weight of loaded dispenser | 58 kg |
