Abstract
Abstract A method of remote detection of an electronic device, such as an electronicomb fuze, which employs active electronic elements includes the steps of transmitting a radar beam through an object which potentially encloses a suspected bomb and receiving the reflections of the transmitted beam, using doppler radar techniques to detect signal phase and amplitude modulations, if any, and processing the reflections to provide an output resulting from any detected modulations which would indicate the presence of active electronic elements within the searched object.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
84 words
A method of remote detection of an electronic bomb fuze having an active electronic element, said remote detection method comprising the steps of: (a) transmitting a radar beam through an object which potentially encloses a suspected bomb having an active electronic element; (b) receiving the reflections of the transmitted beam; and (c) processing the reflections to detect signal modulations, if any, and provide an output resulting from any detected modulation which would indicate the presence of an active electronic element within the searched object.
Claim 2
Independent Claim
84 words
A method of remote detection of an electronic bomb fuze having an active electronic element, said remote detection method comprising the steps of: (a) transmitting a radar beam through an object which potentially encloses a suspected bomb having an active electronic element; (b) receiving the reflections of the transmitted beam; and (c) processing the reflections to detect signal modulations, if any, and provide an output resulting from any detected modulation which would indicate the presence of an active electronic element within the searched object.
Claim 3
Dependent Claim
20 words
The remote detection method of claim 1 wherein said transmitting and receiving are carried out by a monostatic radar beam.
Claim 4
Dependent Claim
20 words
The remote detection method of claim 1 wherein said transmitting and receiving are carried out by a bistatic radar beam.
Claim 5
Dependent Claim
22 words
The remote detection method of claim 1 wherein said transmitting and receiving are carried out by a pass-through one-way bistatic radar beam.
Claim 6
Dependent Claim
24 words
The remote detection method of claim 1 wherein said transmitting and receiving are carried out by a pair of pass-through two-way bistatic radar beams.
Claim 7
Dependent Claim
23 words
The remote detection method of claim 1 wherein said transmitting and receiving are carried out by a pair of superhetrodyne monostatic radar beams.
Claim 8
Dependent Claim
25 words
The remote detection method of claim 1 wherein said transmitting and receiving are carried out by a pair of pass-through two-way superhetrodyne bistatic radar beams.
Claim 9
Dependent Claim
24 words
The remote detection method of claim 1 wherein said transmitting and receiving are carried out by scanning the object while the object is moving.
