Abstract

1459019 Laser range finder ASEA AB 25 Nov 1974 50894/74 Addition to 1362880 Heading H4D In the cloud-height finder of Specification 1,362,880, it is possible for the noise received during interval T 2 to be unrelated to that received (together with cloud echo) during interval T 1 , due to the time interval T 1 -T 2 being too large. To allow the comparison at 25 to be meaningful, the two intervals T 1 and T 2 are now stated to be nearly the same and locked to each other, i.e. T 1 -T 2 =small constant.
