S&DR uses proprietary, unique and reliable methods/technology that can
solve the main problems of almost all security, intelligence,
surveillance and reconnaissance (ISR) systems. S&DRs methods can
be used for real-time working systems and allows to drastically
increase their detection range and reduce false alarm rate. This
method achieves outstanding results by single and multi-channel
signal processing in real time:
Of low-frequency physical signal or low-frequency
amplitude-modulated or amplitude-manipulated physical signal
In case of poor signal-to-noise ratio (SNR up to 1:1).
By arbitrary and unstable shape and amplitude of the signal.
By short duration of the processing record (4-10 seconds).
By missing of the part/parts of the signal (up to 1-2
With extremely low for any practical needs False Alarm rate
not higher than 10-6.
By using the simple micro controller for signal processing.
S&DR has experience of realization of that method by signal
passive hydroacoustic sensors
active ultrasonic detectors
Corresponding method can be easy extended to all other types of
the passive and active systems.
