Abstract
Abstract The invention provides a radar system in which the average power output of the radar transmitter is increased to a value above its rated mean power output during a dwell time during which the radar beam traverses a target of interest. The increase in the average power output of the transmitter typically is of the order of 10 dB and is arranged to be effective for a period of from one to five dwell times, but no longer, with a period of recovery, of at least a substantial fraction of the period of one complete scan, before the average power output is again increased.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
69 words
A radar system including a radar transmitter and a power supply connected to said radar transmitter, said power supply including a power source having means for selectively increasing the power supplied thereby to said radar transmitter to increase the average power output of the radar transmitter to a value above its rated mean power output during a dwell time during which the radar beam traverses a target of interest.
Claim 2
Dependent Claim
69 words
A radar system including a radar transmitter and a power supply connected to said radar transmitter, said power supply including a power source having means for selectively increasing the power supplied thereby to said radar transmitter to increase the average power output of the radar transmitter to a value above its rated mean power output during a dwell time during which the radar beam traverses a target of interest.
Claim 3
Dependent Claim
30 words
A system as claimed in claim 1 and wherein the means for increasing the average power comprises means for increasing the rated mean power in the order of 10 dB.
