Embodiment Construction

[0029] The present invention will be further described below in conjunction with the accompanying drawings and embodiments, and the present invention includes but not limited to the following embodiments.

[0030] The method for realizing the response probability of the Tacan beacon simulator is characterized in that:

[0031] 1. Set the number of digits N (N≥7) of the m sequence and its initial value a N-1 a N-2 …a 1 a 0 (The initial value cannot be

[0032] all 0);

[0033] 2. Set the ranging response probability P (0-85%);

[0034] 3. Convert the response probability P to the initial threshold v0, the initial threshold is:

[0035] v0=round((1-P)·(2 N -1)),( for rounding operation);

[0036] 4. Set the response probability comparison threshold ver=v0;

[0037] 5. The counter of the m sequence shift register is cleared, that is, the count value k=0;

[0038] 6. When the ranging query pulse is detected, the m-sequence shifts once;

[0039] 7. Every time the m-seq...

Abstract

The invention provides a TACAN beacon simulator ranging response probability implementation method. According to the method, m sequences distributed periodically and randomly are adopted, for the m sequences of N bits, (2<N>-1) pseudo-random numbers are provided in each cycle and have the disperse random distribution feature, the values of the (2<N>-1) pseudo-random numbers are compared with the response probability control threshold, and accordingly ranging response pulse output is controlled. The method can be achieved through software, the circuit is simple, adjustment is flexible, the response probability control accuracy is high, and non-response pulses have the random distribution feature under a certain response probability.

Description

technical field [0001] The invention belongs to a Tacan system (Tactical Navigation System) and is used for realizing the ranging response probability of a Tacan beacon simulator. Background technique [0002] The Tacan beacon simulator is a special device for checking, testing and calibrating Tacan airborne equipment. It can simulate the azimuth signal and distance response signal transmitted by the Tacan beacon, and provide fixed position, distance and radio frequency signal level for Tacan airborne equipment. mark indication. [0003] The Tacon beacon simulator receives the ranging query pulse sent by the on-board equipment, demodulates and decodes it through the simulator, passes through the corresponding time delay, and passes through the response probability control circuit to judge whether to output the ranging response pulse. [0004] The response probability is the ratio of the ranging inquiry signal input by the Tacom beacon simulator to the number of output respo...
