Abstract
Abstract A method of receiving pulses of the M.L.S. type and a system for implementing this method. The method comprises a dividing stage for dividing the received pulse into zones (Z1, . . . Z8). A mean value is determined of the samples within each zone in order to obtain the points PI(1) . . . PI(8). The straight line DR at best passing through these points provides the instant (tMAX) which is the "time" of the pulse.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
105 words
A method of determining the time when a pulse is received, comprising the steps of: a. sampling the instantaneous value of the pulse at a plurality of different times; b. determining the difference between the maximum value sampled and a predetermined threshold value; c. dividing the difference into a plurality of zones; d. determining the values and times of the samples in each zone; e. determining from the values and times of the samples in each zone a mean value and a mean time; and f. determining from the mean values and mean times for the respective zones the time when the pulse was received.
Claim 2
Independent Claim
105 words
A method of determining the time when a pulse is received, comprising the steps of: a. sampling the instantaneous value of the pulse at a plurality of different times; b. determining the difference between the maximum value sampled and a predetermined threshold value; c. dividing the difference into a plurality of zones; d. determining the values and times of the samples in each zone; e. determining from the values and times of the samples in each zone a mean value and a mean time; and f. determining from the mean values and mean times for the respective zones the time when the pulse was received.
Claim 3
Dependent Claim
15 words
A method as in claim 1 where the pulse time is determined by linear regression.
Claim 4
Dependent Claim
25 words
A method as in claim 1 or 2 where zones which do not produce significant information are eliminated from the determination of the pulse time.
Claim 5
Independent Claim
110 words
An apparatus for determining the time when a pulse is received, said apparatus comprising a processing unit comprising means for: a. sampling the instantaneous value of the pulse at a plurality of different times; b. determining the difference between the maximum value sampled and a predetermined threshold value; c. dividing the difference into a plurality of zones; d. determining the values and times of the samples in each zone; e. determining from the values and times of the samples in each zone a mean value and a mean time; and f. determining from the mean values and mean times for the respective zones the time when the pulse was received.
Claim 6
Independent Claim
110 words
An apparatus for determining the time when a pulse is received, said apparatus comprising a processing unit comprising means for: a. sampling the instantaneous value of the pulse at a plurality of different times; b. determining the difference between the maximum value sampled and a predetermined threshold value; c. dividing the difference into a plurality of zones; d. determining the values and times of the samples in each zone; e. determining from the values and times of the samples in each zone a mean value and a mean time; and f. determining from the mean values and mean times for the respective zones the time when the pulse was received.
