Abstract

The invention discloses a respond wireless interference signal generator and a method thereof. According to the device, a PDA (personal digital assistant) connected with a DSP (digital signal processing) controller is connected with a programmable pulse time delay circuit, a frequency synthesizer and a DDS (direct digital synthesizer) respectively; the frequency synthesizer outputs a local oscillator signal to the DDS and a signal receiving circuit; a time delay circuit is connected with the control end of a DFRM (digital radio frequency memory) of which the input end is connected with a receiving circuit and an antenna; the output end of the DFRM is connected with an IF (intermediate frequency) mixer connected with a clutter generator by a numerical control attenuator; the output end of the IF mixer is connected with a plurality of signal output circuits by a power distributor; and each signal output circuit is also connected with the DDS, and the tail end of each path of output circuit outputs a modulated simulation target signal through the antenna. The respond wireless interference signal generator and the method thereof can perform programming process according to an aerial target motion rule, performs deception or checking on radio positioning equipment by the directed radiation of received same frequency and signal modes, and are suitable for various kinds of radio positioning equipment.

Description

[0001] technical field [0002] The invention relates to the application of electronic technology, in particular to a response type wireless interference signal generating device and a method thereof. Background technique [0003] At present, the method used for radio positioning equipment signal simulation is mainly to extract radio frequency information from the radio positioning equipment host in a wired manner, add moving target elements by the simulator, and radiate into the air through the antenna at a short distance after power amplification, and the radio positioning equipment receives The signal is analyzed and detected to test the performance of the radio positioning equipment. This mode is only suitable for radio positioning equipment with Doppler detection performance, and is restricted by wires, the working distance is limited, and the application range is very small. This method is dependent on the analog signal object, and can only be used as a signal source ...
