Radar Target Imitation Equipment (hereinafter Equipment) is intended for a signal (on the air) imitation of an aerodynamic air target of a set type for radar stations (RS), radar scan/tracking of surface-to-air rocket systems (SRS) and aviation rocket systems of ntercept (ARSI) as well as radar target seeker (RTS) of and aviation operating missiles. The Equipment is used during trial flights and shooting tests SRS (ARSI). The Equipment performs the functions being a part of unmanned aviation vehicle (UAV), that includes an unmanned aircraft-target (UA-target) with an autonomous operating system, surface system of operation and indication, parameters recording equipment. The Equipment may be used autonomously for surface checking of RS SRS (APSI) and radiolocating RTS.
Operation principle. The Equipment performs the functions or radar imitation of aerodynamic target of a set type by probing signal reception from RS SRS (APSI) or radiolocating RTS rocket, its analysis, allotment of required types of modulation and radiation into the space. The Equipment is designed by a retransmitting principle that provides its high acceptance rate (practically unlimited quantity of simultaneously operated RS (RTS). The Equipment ensures the record of flight information that can be used for an operative or postflight analysis of operability, operation regimes of RS (RTS) and their parameters. The Equipment can be used in a special regime of imitation of a moving target at a lowered launch power for a surface operability checking of RS SRS (APSI).
Besides, RTI ensures:. – imitation of Rayleigh fluctuations of Image tubes typical of the case when linear dimensions of the target of a complex geometric shape are much bigger than a wave length of a probing signal;
– imitation of airframe and modulation components of the spectrum of the reflected signal, that is typical of radar observation of an aerodynamic target having rotating parts (airscrew blades, compressor blades, turbines of a propulsion device). The Equipment provides: - radiation of a signal of calibrated non- fluctuated capacity (regime “Standard”) for experimental evaluation of sensitivity of reception path of RS SRS (APSI);
– receiving and calibrated measurement of pulsed power of a probing signal RS, that provides experimental evaluation its energy potential;
- imitation of a reflected signal from a real aerodynamic target of a geometrical shape with fluctuated ECS;
- imitation of “airframe” and “modulation” components of the spectrum of the reflected signal (modulation components occur on the account of re-reflection of the probing signal from mechanically rotating elements of the target: airscrew blades, turbines blades, compressor etc.;
