Receiver Sequencing via Random Probability Law for Signal Interception
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current receiver sequencing methods for intercepting electromagnetic signals, particularly radar and communication signals, are inefficient due to the need for long-duration missions and are not optimized for non-permanent transmissions, leading to missed signals and high costs. Additionally, existing methods are complex and require precise knowledge of signal characteristics, making them unsuitable for diverse scanning types and limited hardware resources.
Innovation Solution
A method for sequencing a receiver that uses random drawing without memory to generate listening instructions, optimizing the probability of intercepting signals from various scanning types by adjusting listening frequency bands based on probability laws that minimize signal non-interception, allowing for efficient signal acquisition across a wide frequency band with limited resources.

Engineering Contradiction Analysis
1Measurement precision
If a narrow band receiver is used to detect radar signals, then the ability to detect and analyze signals is improved, but the coverage of the entire frequency band is lost
Solution Approach 1:
The frequency band is divided into multiple narrow sub-bands, each monitored by a separate receiver. This allows the system to maintain narrow band detection capability for signal analysis while covering the entire frequency spectrum through multiple receivers operating in parallel.
Solution Approach 2:
The system transitions from a single receiver covering wide frequency band to multiple receivers distributed across frequency dimensions. This dimensional expansion allows simultaneous narrow-band detection capability and broad frequency coverage by adding the receiver dimension to the frequency spectrum.
2Area of stationary object
If multiple receivers are used to cover the entire frequency band, then the frequency coverage is improved, but the economic cost increases
Solution Approach 1:
Multiple receivers are combined into a unified system that shares processing resources and coordination mechanisms. The receivers operate as a coordinated array, pooling their detection capabilities to cover the entire frequency band while sharing the economic burden through centralized management and resource allocation.
3Reliability
If a regular scanning sequence is used to intercept radar signals, then the interception of all signals is ensured, but the mission duration increases
Solution Approach 1:
The scanning sequence operates in periodic cycles, systematically cycling through frequency bands in a regular pattern. This periodic action ensures that all frequency bands are eventually covered and signals are intercepted with high reliability, while the repetitive nature of the cycle allows for efficient time management and reduced overall mission duration compared to exhaustive sequential scanning.
4Measurement precision
If the receiver listens to frequency bands for long durations, then the detection of radar signals is improved, but the time available for other signals is reduced
Solution Approach 1:
The total listening time is segmented and distributed across multiple frequency bands simultaneously. Instead of dedicating long continuous time to a single band, the system allocates time slots across multiple bands, ensuring sufficient detection time for signals while maintaining progress across the entire frequency spectrum.
Solution Approach 2:
The system maintains continuous useful action by simultaneously monitoring multiple frequency bands. While one band is being analyzed in detail, other bands are being monitored in parallel, ensuring that time is never wasted and that signal acquisition continues uninterrupted across the entire frequency spectrum.

AI summary
The method (10) involves generating a set of successive listening instructions (110) that is to be carried successively by a receiver. The listening instructions are obtained by random pulling without storing the instructions. Each instruction is allowed to define an elementary listening duration and a listening waveband among a set of listening band frequencies. The receiver is allowed to regulate its reception waveband for the duration. The random pulling is performed so as to comply with a law of listening probability defining listening probabilities of a set of listening wavebands.
